One of the limitations of a large scope war film is that you lose the human story that attracts audiences to the event. When something like a war - huge in scope by nature - is depicted on-screen (and likewise in education), you need a human focus to even begin to comprehend the magnitude of the real-world horror. Thomas does that here with the exceptional real-life stories of these women. It falls into the traps that too many biopics suffer, but with a great ensemble cast including Katic, Linus Roache ('Mandy') and Apte's first foray into American cinema, there is space for this film to exist and prosper. At the very least, these real-life heroic women deserve your attention.
