Margaret (2011)
A terrific, evolving, and in-obvious story line mixed with a lead performance by Anna Paquin to die for makes "Margaret" fabulous. See it for her performance alone.
If you think this is a new movie you'll notice some famous actors who look rather young--Matt Damon in particular in his role as a likable high school teacher. That's because it was filmed in 2005 (and got held up in post-production). Even so it doesn't feel dated. The main themes hold up really well, and are told with unusually frank terms. Many people really are just greedy and selfish at heart.
The key event happens early on and in a way can't even be mentioned here. But it's safe to say that Paquin, who's character is called Lisa Cohen, at first takes a false stance in a moment of crisis and compassion. But the truth of the matter eats at her, and against the rising tide of people who prefer the lie she becomes increasingly principled. In the end it is almost everyone who is morally corrupt, even in his own way her teacher.
There is one lurking problem to the movie that really hurt it. One is the way the initial crisis is filmed (with Mark Ruffalo as a bus driver). It is exaggerated and makes the circumstances leading to tragedy unlikely just when the rest of the movie depends on likelihood. Since this is the lynchpin of everyone's reactions later on, it matters rather too much to ignore.
But the rest of it, from the main plot and Paquin to the various sub-plots including a romantic affair her mother has and some political conflicts about Arab-Israeli relations and the 9/11 events, is all really sharply delineated and well acted. And it's written with a good ear for dialog. It simply makes sense. The fact that there is no silver lining here, and that people are shown so obviously ugly below the surface, is harder to do than you might think. All admirable stuff.
