In the last moments of World War II, a secret Nazi space program evaded destruction by fleeing to the Dark Side of the Moon. During 70 years of utter secrecy, the Nazis construct a gigantic space fortress with a massive armada of flying saucers.
Such wasted potential. The beginning and end of this film have the makings of a fantastically terrible movie, but like so many similar cheesy films it falls apart in the middle, becoming just another bad movie. I think the problem is, many of the creators of these types of films come up with a awesome & ridiculous premise and a foolish ending, but forget that there needs to be a movie in-between those ideas.
There's a lot of stuff copied from other films here, others have mentioned some of them, and I'm okay with that. I don't really think those things serve any sort of higher purpose, or homage if you will, but from my point of view they work because they make the movie intentionally bad. The Sarah Palin parody doesn't work at all, it's just unfunny & lazy, and I'm not saying that for political reasons... I'm Canadian and Palin & her tea party cohorts are certifiably nuts. However, these jokes about Palin, her style of politics, her stupidity, and American stereotypes have all been made before in smarter and more humorous ways.
One point that's especially worth praising is the special effects. This has to be one of the nicest looking space battle scenes in a movie of this type (cheesy b-movie), that I've ever scene.
