Awesome concept, but poorly executed
SPOILERS!!
The first of the movie dragged on, taking too long to introduce the characters. And since one of them is a Nazi spy, do you really think he'd take all his Nazi identification while posing as a US soldier? But the absolutely stupidest, unnecessary and just plain "what the *beep* moment was when the giant robot withdrew his "dick" and raped the captain. Totally not needed in this movie.
Let's hope the sequel, tentatively called "The War With God" doesn't have stupid scenes like that.
