I thought that the moment they actually showed an alien it crossed the line into cheesiness.
Oh, and I should ask... of those of you who've seen the movie, did anyone think that the aliens were there peacefully and were actually trying to help the inhabitants of earth? A friend who I saw it with was convinced that this was the case, and that the people just misinterpreted the aliens' presence. I have told him numerous times that he is wrong, but I'd like to know if anyone else had even considered this interpretation.
