"Valkyrie" swoops down on conventional wisdom

Watching Valkyrie immediately makes me realize that my "survey" understanding of WWII is woefully inadequate. We have a sort of blimp's eye view of wars sometimes, where we assume that it was purely manicheistic: the bad guys wore black and the good guys wore white, and the good guys won. With real life never quite panning out like that, Valkyrie does an excellent job of showing one of the many insurrection attempts on Hitler's Germany, with politics and paranoia that smacks of V for Vendetta. Director Bryan Singer was on his A game, which means I can finally forgive him for not directing X-Men III.
What I appreciated was the amount of minutia surrounding the actual attempted coup. In some movies, such as The Perfect Storm, you have a level of circumstantial detail that builds the tension you feel and the connection you have to the characters. Yet at the end of Storm, we find out that no one lived to tell the tale. I felt completely jipped, especially when the movie touted itself as "based on a true story." Story, indeed. Now, I can't stomach the melodramatic moment in Storm, knowing they are all hearsay and guesswork.
In Valkyrie, however, those very details are true; the product of meticulous research, historical record, and even reenactments. This makes the film much more enjoyable, especially since it is surrounding such an important time in our recent history.
If you are going to Valkyrie for Mission Impossible you will be sorely disappointed. If you are going in order to see a facet of history that has almost entirely slipped through the cracks of the modern historical canon, then you will enjoy it. It is well-paced, well-acted, and has an excellent cast. That said, the only drawback I see will be felt by the producers, and that is that - given the way that the story unfolds - I don't see a huge market for repeat views, so I predict mediocre DVD sales. I would watch it twice, but I could understand how a single viewing would suffice for most.
Too, there seemed to be a slew of accents: some trying for German, some more British, and Tom Cruise sticking with, well, Tom Cruise. While it would have been nice to enforce a bit of consistency here, it was only a minute detail that goes largely unnoticed.
Any evidence to the contrary is welcome in the comments section, as are all other observations, opinions, etc.
