Attempting to describe this film's plot would be futile (I tried in my review of "Eternal Sunshine" and it didn't work out too well) for it includes too much to make sense on paper. There is a letter mix-up, a visitor who may not be who he people who invited him remember him as, a forbidden love and raging jealousy which leads a young girl to make a horrifying accusation which threatens the life of one of the star-crossed lovers. There was really nothing about this film that didn't work: it had great music, great acting, a wonderful script, and a brilliant conclusion that is heartfelt without being sappy. Another strong suit of the film is to replay multiple events from various people's points of view, making the event more clear each time that it is shown. I will say that the first half of the film is stronger than the second half. The front is set up like a romantic thriller and the second half is more of a war film, which weakens it ever-so-slightly, but even its weakest points are well above average; not to mention the second-half's hair-raising twist. "Atonement" is a great ecploration of love, childhood innocence and, ultimately, sorrow. As far as content goes, there is one sex scene that does not contain nudity but is rather extensive, as well as a few disturbing war images. It is appropriate for most teens, but it probably won't really interest them; they may find it rather slow and tedious (even though they are sadly mistaken.) Just brilliant.
