There's a lot to hate about this film. It's cheap, there's too much bad CGI, the director is obviously a big fan of Tarantino style post modernism, but then again, there's a lot of action, and the film most definitely is tongue in cheek. People reviewing this have scoffed at the girl with a camera jammed between her boobs, squeezing them together to get a picture. Here's a thought: It was probably a joke to begin with.
What you have is four GIs sent over to Europe to rescue an undercover agent who's there to spy on some Nazi occult goings on. There's the ex-priest, the good guy, the redneck racist and the Ghost Dog style black GI with a samurai sword. They all make their way to the Nazi base, where Claudia, the undercover agent, is working.
This film (including the soundtrack) is a huge homage to seventies and eighties films (but not Nazisploitation films as noted by another reviewer). Someone else here thought the 'girl on a bike' effect was hilarious but it's a clear copy of Tarantino's same thing from Pulp Fiction.
And that's the problem with the film: There's too much by way of Tarantino's 'Grindhouse' influences, with the ageing of the film and such like. But then again, no one bores you for twenty minutes with a soliloquy about black widow spiders (I hate that crap!).
Then again, the soundtrack is spot on, with it sounding like a mix of Ennio Morricone and Tangerine Dream. I choose to accept there's a huge amount of irony in this film, and kind of enjoyed it (I'm beginning to think even the CGI was used ironically).
Maybe I'm just in a good mood. Watch it or not, I don't care.
