Okay, this one has been one of my favorites for half my life now, which means since I was 16. It should be judged by what it IS and not by what it ISN'T. This is NOT a Sci-Fi movie! This is NOT an invasion from outer space movie, this is simply a funny-as-hell movie with as many stand-up comedians as you can find! C'mon, nobody actually thought that painting up the faces of some stand-up comedians in green and making them tell jokes about the entire world population would make them believable aliens, they just thought, and were right to think, that it would make them funny as hell, without using them as stereotype comedians. A very funny movie, unappreciated by people with different expectations.
