Let's face it, it's a B movie with a lot of unnecessary subplots, car chases and characters, what it does right though is delivers the theory of a hollow moon which has a basis, because the moon did ring like a bell. You have typical Roland Emmerich: the military act like idiots, everything that is happening is a complete madness and everything is done last minute on a technology that should fall apart but doesn't, in a addition to that there is an almighty enemy...
The story doesn't take itself seriously, the main cast tries to do it's best, so it's watchable if you like Sci Fi, and if you don't, well don't bother ...
