I saw the movie.
Whatever you think of Cruise (I thought he did well), the movie has a lot of talented supporting actors. Historical accuracy is hard to judge as I'm not an expert on Hitler assassination plots, but as a piece of semi-historical entertainment the movie is good, though not excellent (few movies reach that mark). I thought the story could have benefited from more character development for Staufenberg. It begins in Africa in early '43, so you don't have any sense of the character's origins, what kind of man he is, where he grew up, etc. The Merlin-engined 109 in the hangar is kind of a pity, but what are ya gonna do? For that matter, it's not a movie to see if you're one of those that love to identify military hardware.
