Finally watched this movie, on Netflix. All I can say, is what a wasted opportunity. The special effects were well done, but the plot and dialogue were cringe-inducing. Terence Howard and Cuba Gooding Jr could have been replaced by mannequins, their acting was so wooden - of course, the scripting didn't give them much to work with.
Then, there was the complete implausibility of several action sequences. Blowing up a locomotive and turning a destroyer into a blazing inferno with a few rounds of .50 cal. just weren't going to happen. I could accept the shooting down of Me 262's as "artistic licence", although the Tuskegee Airman weren't credited with such kills.
I'm glad I never bought the BD.
