'Spring' is a decent watch, if nothing all that more. I personally didn't really click with this 1970 Estonian picture. I imagine that has a lot to do with the fact that I am, indeed, not Estonian and/or not from this sorta era, as it is a movie that is heavily nostalgia-driven. I will say that it is well made for its time, at least. The main reason for my lack of connection, aside from the aforementioned, is actually the main characters, both those portraying and being portrayed. I found the kids quite annoying, all of them in fact; especially the more, eh, 'emotional' ones. The flick does go for the 'kids will be kids' angle, but even so I don't think they needed be quite so irritating. The actors aren't the best either, though I can look past that without the noted issue. The adult actors are the better cast members. As somewhat of a completionist, I now feel the need to check out the three sequels; which, interestingly, were released in 1976, 1990 and 2020; ought to make for an interesting time capsule of sorts through Estonia's recent movie decades.
