An absolute masterpiece. At once the most horrifying and humanistic film I've ever seen. Not only Elem Klimov's opus magnum, but certainly one of the best films to ever be made in the USSR. In my opinion, one of the greatest reflections on the theme of war, not only in cinema, but in any medium.
It's fitting that the title comes from the Book of Revelations, because Come and See looks like a door to hell has been flung open: a surreal nightmare where all moral stability has evaporated into chaos—even simple tracking shots through mud and forests can make you question your sanity. This is a devastating film, uniting us always with its hero's shellshocked gaze. His inner and outer journeys leave you shattered.
The personal tragedy disembogues into the greater tragedy, which turns the focus to the greater evil and finishes with the personification of evil. It's structurally beautiful. I lack the adjectives to characterize this, because I feel they will reduce it, but I am absolutely devastated. Perfectly balanced innocence, malevolence, horror, poetry, mysticism and even light-hearted humor. Damn.
Deciding to watch this film seems a desire to put yourself through the pains of history (albeit through the mediation of film) so as to understand their weight, see them afresh. It seems, given the historical footage montage in the denouement of the film, that creating "Come and See" was in part a desire to give life to historical atrocities, so as to keep them fresh in our minds at present.
