Spoiler: Hitler dies!
I thought it was excellent, but it's one of those movies you watch once and then loan to all your friends and don't watch again for 5 years. It's emotionally draining, the desperation and delusion. Not to mention that just about everybody is killed. Never thought I could feel pity for a bunch of Nazis and least of all Hitler, but this movie does a good job of making you feel sorry for them as a human and then turning 180 and renewing your hate for the system they had invented and the actions that they had perpetrated.
