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...
