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.
