Just got back from seeing Valkyrie. I give it two thumbs up 
I prefer that German characters at least roll their Rs, but the fact that Cruise's character began the film speaking German and then faded into English was quite acceptable. The glass eye kind of creeped me out 
Even though I knew the ending, it didn't take away from the film. I'll definitely add it to my DVD collection when it's released. I thought that the guy playing Himmler looked very much like him. We didn't have a bad looking Hitler either, though he could have used a bit more of the "crazed" look in his eyes.
I was surprised to learn that Von Stauffenberg orgiinally attempted to execute the plot on my birthday, 15 July. Interesting
In any event there were a lot of nazis running around in the film, and they're my favorite villians.
