If it wasn't trying to be "One Flew Over the Cuckoo's Nest," it would have been a lot better. As it is, I just feel let down by the excellent (and short) action scenes. It needed more B-25's and Steampunk Zombie Krauts. Now, two hours of that would've been amazing.
Unfortunately, the movie didn't have enough like this.
It's weird that the parts that are set in the real(er) life were the parts that strained credibility.
Oh, and by the way, there was quite a bit of 1911 action going on in there, so it was good that I saw it on the 100th anniversary of the Army's adoption of the 1911 pistol.
