Well I can't call it different. I've never actually seen a movie with a plot like this, but it did feel exactly like a low budget cheap drive in comedy/sci-fi show and...kudos. The best part about this is that, at no point in time, does it take itself seriously. It knows exactly what kind of movie it is and delivers the goods without any pretense, without any attempt to be a better film. It seems like everyone involved knew the score and did their parts to sell the movie for what it is, and not what they think it could be. So, what you have is a comedy that is ferociously entertaining. It's a stupid plot with a cheesy script and equally inane characters and it pulls it off brilliantly. The end result is, when you sit down to watch it, you're going to laugh and be entertained and the time is going to fly by. But, you are going to hate it if you walk in expecting 2001, an enormous budget, or a deeply profound political lecture...but then, if you walk in expecting any of those things why are you watching a movie about Nazis on the moon?
