Rain Man — way overrated here. As Tropic Thunder pointed out, playing an inspirational disadvantaged character is not actually that difficult and is a cheap way to get people to think highly of your movie. Also, the bad guys were right and he really is a danger to his kids.
Valkyrie — way underrated here. Way less BS hollywood liberties taken with the story than most other historical-esque films. The movie was more or less how it happened. Cruise was a dead ringer for Stauffenberg. And one of the few movies smart enough to realize that the audience knows what language people are speaking in and doesn’t need horrible-sounding fake accents.
