I enjoyed this film. There, I said it. I have watched it twice and will again at a future time. I see it more as suspense rather than as an action thriller, the difference Hitchcock explained between a bomb going off and the tension of wondering if it is going to go off. A bulging muscled hero or a bulging cleavaged heroine wouldn't have improved it in my eyes. This is a different sort of alien invasion movie. In fact, it almost feels to me like the invaders dropped in on the planet like drunken tourists and now find they aren't able to fit in or leave but are instead stuck in one bar fight...
