I love this movie. I don't know why, since it's one of the most ridiculous things ever committed to celluloid. It's not great science fiction, but it's accidentally hilarious and completely entertaining. It's short running time probably helps as well.
It's often called one of the worst films ever made, but as we have seen by now, plenty of movies are far worse, and they usually have huge budgets. This one is so bizarre and at least tries to live up to it's premise, even if it works better as a comedy. If you don't like it, you must be a foolish hu-man and should recalculate.
