Interesting and reasonably well-made, but morally questionable in how it presents some of the material

I'm sure it all started with some distinguished psychiatrist and a roomful of people, and the brilliant idea arises of a new way of studying nature versus nurture. "Okay, we’ll separate these kinds and watch them grow." This is nightmarish, Nazi shit.

• Elyse Schein and Paula Bernstein quoting Bobby Shafran; Identical Strangers: A Memoir of Twins Separated and Reunited (2007)

What is the primary factor in making us who we are? Were the truly great figures of pure evil – Elizabeth Báthory, Adolf Hitler, Harold Shipman, Peter Scully, Adam Sandler – always destined to become who they became, or are there to be found moments and influences in their environment which turned them into the monsters with whom we're familiar? If our destiny is genetically encoded at the moment of our conception, can we really say there is such a thing as human agency? In short, it's the age-old question of nature vs. nurture; does biological determinism supersede free will? Focused on precisely these questions, twin studies involve researching twins to so as to compare and contrast the importance of genetic factors against environmental factors. A branch of behavioural genetics, when most people hear the term "twin studies", they probably think of Josef Mengele's sickening experiments in Auschwitz. However, these experiments were inhuman and not even remotely typical of scientifically approved twin studies, which are an accepted, if somewhat controversial, attempt to determine the etiology of differential psychologies in individuals who are genetically similar. And these are the murky waters charted by director Tim Wardle's Three Identical Strangers. Covering some of the same ground as Elyse Schein and Paula Bernstein's book, Identical Strangers: A Memoir of Twins Separated and Reunited (2007), and Lori Shinseki's documentary The Twinning Reaction (2017), the film presents a bizarre stranger-than-fiction story, which begins as a light-hearted human-interest piece before taking several darker turns. A big hit at the 2018 Sundance Film Festival, where it won the US Documentary Special Jury Award for Storytelling, Strangers is hotly tipped for Oscar glory, and has been almost universally well-received by critics (96% approval on Rotten Tomatoes at time of writing). However, for me, although the fascinating central story is undoubtedly gripping, there are just too many egregious problems in the telling, including an excess of distasteful sensationalism; a dearth of contextualising scientific information; overly simplistic ethical, moral, philosophical, and esoteric conclusions; stylistic drabness; and an overreliance on plot twists, which often forces the filmmakers to manipulate the material beyond what you would expect normal of a documentary. The film begins in 1980, as Bobby Shafran heads for his first day at Sullivan County Community College in New York. However, upon arriving, he is taken aback by how friendly everyone seems, with people acting as if they know him, and welcoming him back. Meanwhile, Bobby is approached by second-year student Michael Domnitz, who had heard that his friend Eddy Gallan had returned to school. Coming to say hi, Domnitz is stunned when he encounters Bobby, who he now sees is identical to Eddy. Learning that Bobby was adopted, and was born on July 12, 1961, Domnitz tells him he has a twin brother. After Bobby and Eddy met, their story is reported nationally, and reading a newspaper article about the twins, David Kellman is stunned by what he sees – he looks exactly like them, he too was adopted, and he too was born on July 12, 1961. The twins were, in fact, triplets. The trio quickly bond, move into an apartment together, and eventually open a restaurant in New York, Triplets Roumanian Steak House. Becoming minor celebrities, they appear on talk shows across the country and have a cameo in Susan Seidelman's Desperately Seeking Susan (1985). However, they and their families are puzzled as to why they had been separated, and why their adoptive parents had not been told they were triplets. Was it a coincidence that Bobby had been placed with an affluent family, Eddy with a middle-class family, and David with a blue-collar family? Did the regular aptitude and psychological tests they received as children, part of what their parents were told was a "routine childhood-development study", have anything to do with their separation? What was the involvement of one of the country's largest social service agencies, the Jewish Board of Family and Children's Services? How much did New York's most preeminent Jewish adoption agency, Louise Wise Services, know? How was Dr. Peter B. Neubauer of the Jewish Board's Child Development Centre in Manhattan involved? How did the triplets' birth mother fit into what happened? As they begin to investigate, they soon stumble upon a series of shocking secrets that would change their lives, and the lives of many others, forever. Three Identical Strangers starts out as jaunty as you could possibly imagine – Bobby heading off to college as Rainbow's "Since You Been Gone" (1978) plays on the radio. Within the first half-hour, the film also features cheerful montages cut to Katrina and the Waves' "Walking on Sunshine" (1983) and Kim Wilde's "Kids in America" (1981). Ominous this most certainly isn't; with the early parts of the documentary presented as if this were a feel-good story no different from any you might see on daytime TV shows such as The Phil Donahue Show or The Oprah Winfrey Show. This makes sense, given how much time the triplets spent on such TV shows. Indeed, so laidback are these early scenes that the whole thing could easily be the opening episode of a sitcom about three likeable guys accidentally learning they're brothers and going on a madcap adventure together. Another noticeable structural element concerns what Wardle and editor Michael Harte referred to at a Q&A after a screening in Dublin as a "past tense" and a "present tense". The past tense section covers roughly the first half of the film, running up to the end of the first round of interviews, which were conducted from 2011-2015. The present tense section then picks up in 2016. The transition between the two is pretty obvious, but it's worth mentioning as it's not something you usually see in a documentary. Half-way through the film, Wardle thanks Bobby and David, who are being interviewed separately, and they say goodbye, get up, and leave the room. It's very unusual to see a documentary film drawing attention to its own artifice in this manner – the furthest most will go will be to include the interviewer's voice, but even that is relatively rare. By featuring a scene like this, especially so early in the film, Wardle and Harte are alerting the audience to the fact that something has changed, and from here on out, things are going to be in a different register; their use of tenses to describe this shift is as accurate a description as you're going to get, almost as if we've moved from pre-recorded material to live footage. It soon becomes apparent that the second half of the film is much less focused on narrative than the first, whereas the first is relatively light in the way of moral, ethical, or philosophical musing. The second, in contrast, becomes increasingly esoteric as the brothers struggle to find out the "why" of what happened to them. Both halves feature a mixture of talking heads, archival footage, and reconstructions, but almost all of the reconstruction material and most of the archival footage is confined to the first half, which is a good indication as to the different contents, and all in all, it's a well-managed structural technique. One such technique, however, which doesn't work is Wardle and Harte's decision to repeat certain footage at key moments in the film. So, for example, when an important bit of information is revealed in the present, there are "flashbacks" to the relevant moment(s) in the past whose meaning has been altered due to the new contextualisation – think Bryan Singer's The Usual Suspects (1995) or Christopher Nolan's Memento (2000). The problem with this is two-fold; a) the technique is used far, far too often; and, b) it's sensationalist and manipulative. In a fiction film, this kind of thing can work both aesthetically and thematically, because fictional narratives are focalised, told from either a singular or multiple points-of-view. Within this context, repeating previously seen footage can work very well. Documentaries are not focalised (or they shouldn't be), and as we once again hear dialogue we heard sometimes only 15 minutes previously, the technique (which is not even done in an especially artistic manner) cheapens the whole process, as if the director is literally appearing on screen to remind us not only of why such and such a piece of information is important, but of how it should re-shape our perception of previous events. This goes beyond hand-holding, and into brow-beating. And with what is this brow-beating concerned? The film really has two major themes; morality/ethics and nature vs. nurture. In terms of morality, at the Dublin Q&A, Wardle referred to the scientists behind splitting the triplets up as succumbing to "noble cause corruption", arguing that they probably set out to accomplish something laudable, but were not above using unethical means to do so. That Neubauer, in particular, could allow this to happen is especially ironic, given the obvious touchstone of Nazi experimentation with Jewish prisoners, and his background as an Austrian Jew who had fled the Holocaust. It does, however, seem strange that when examining the morality of what was done to the brothers, Wardle makes no mention of David Reimer, a male who was reassigned as a girl in 1965 when he was only a few months old and raised female, based upon dishonest advice given to his parents by psychologist John Money, who was attempting to prove that gender identity is learned. As there are a lot of parallels between the brothers' stories and Reimer's, and between Neubauer and Money, including a reference or two would have helped contextualise things. As to the question of nature vs. nurture, initially, events seem to point very much to nature – the brothers all smoked the same brand of cigarettes; they had all been amateur wrestlers; they had the same taste in women; they had similar speech patterns. The media at the time ate this up, with their appearances on talk shows designed to leave the audience stunned at their similarities. However, as the documentary goes on, the argument shifts, with the brothers themselves admitting they emphasised their similarities at the time, and the media was more than happy to ignore any differences, leading to what was apparently a clear win for biological determinism. As time went on, their differences began coming to the surface, and ultimately, the documentary very much argues in favour of nurture. However, how it goes about establishing this argument is extremely questionable, with Wardle sliding more and more into sensationalism. So intent is he on controlling our perceptions that he leaves out a massive piece of information until such time as he deems it pertinent to reveal, and when he does so, he explicitly tells us what to think about it, pushing us to one specific response, when the event cries out for a more ambiguous presentation. It's difficult to go into any of this without straying into spoilers, so consider the rest of this paragraph a spoiler. Essentially, Wardle paints the suicide of one of the brothers as unquestionably the result of his adopted father's harsh disciplinarian parenting, a father who is still alive, and who appears in the film. Wardle and Harte do this by cutting from a clip of that father wondering if he had a role in the suicide to one of the other brothers basically saying, to paraphrase, "I'm still alive because my parents weren't as strict as his." Blaming his death entirely on parenting in this manner is facile, grossly overly simplistic, and offensive. In fact, the way Wardle handles the suicide in general is deplorable, teasing it and teasing it, before gleefully revealing it for maximum tabloid-esque shock value. The sense of Wardle manipulating the material isn't helped by the fact that the absence of the third brother from the talking head interviews tips off the audience from the get-go as to where the story is heading. Why not just state it right up front, cutting back on the silly twist element of the narrative? It's not like people would get up and walk out upon seeing a "spoiler" like that at the outset – this is a documentary, not an M. Night Shyamalan film. There are other problems, however. Aesthetically, the documentary is drab and dull, almost lifeless. With nothing cinematic about it whatsoever, it could easily be a report from a TV news magazine show, designed for maximum exposure rather than artistic inventiveness. The recreations are bland, and the talking head interviews are flat. Additionally, twin studies are a recognised and accepted scientific practice, but Wardle is so intent on making sure we are appalled at what happened to the brothers that he provides almost no context whatsoever. If he had spent less time trying to steer the viewers' emotions and more in providing a broader theoretical framework, the film would have worked much better, allowing the audience to find their own position in relation to what was done rather than simply following the director's lead. He also ignores a great deal of potentially interesting material. For example, why did their restaurant fail? According to the film, it was because of "different work styles". Which means absolutely nothing. Why does he not go into this a little? In fact, we never really get any sense of what the brothers' day-to-day life was like after they found each other. When they moved in together, how did that feel, for example? It's as if he doesn't want to dig too deep into anything just in case he finds something that might not fit into the grand narrative he's constructing. The story of Three Identical Strangers poses fascinating questions about nature vs. nurture and the morality of certain types of research, but the film is so intent on the "nurture" answer that Wardle's subjective opinion comes across far more than it ought. More interested in driving home the shock value of some of the events than providing a penetrating documentary about free will vs biological determinism, there is little here that a reader wouldn't be able to find on Google. Given the outrageousness of the material, that Wardle has made such a conventional film is disappointing. It's an interesting enough piece, but that's more to do with the fascinating subject than the presentation, with the whole thing feeling a little too much like a Wikipedia entry.
