I just watched this movie yesterday, and the only thing I didn't like was the fact I saw it yesterday. I wish I had seen it so I could tell people about it during its theatrical run.
It won the Academy Award for Best Adapted Screenplay, and after watching it, it was easy to see why. Its message was simple but powerful, timely but timeless.
A movie like this either sinks or swims on the performance of its lead, and the actor in this, a kid making his acting debut, absolutely nailed it.
