Battlefield Earth was really, really bad, for so many reasons.<br /><br />First off, in the book the aliens believed that humans had long since become extinct, and have been extinct for a thousand years. In the movie, the humans have been slaves for a thousand years, so it really is ridiculous when Travolta is amazed that they can be taught anything, or that he thinks they like raw rats. Also, in the book the guns and airplanes in storage under the mountain are as useless as they were in the three hour war a thousand years ago when the aliens first arrived and destroyed what they thought was all life on Earth. Also, in the book it goes into much more detail about exactly how the aliens really hate each other and don't trust each other and are screwing each other over whenever they can. In the begining, the Travolta character isn't busted for doing someone's neice, as if that hasn't been overused to death in every other movie that should never have been made! He is being screwed over because he is too good at his job and has alienated every alien on Earth (wah wah wah) To be honest, though, I just had to stop reading the book half way through because it just became too ridiculous (canibal mutant Rhodesians that worked secretly for one branch of the aliens so the rest didn't know about them, an impromptu peace conference of all alien races just happens to crop up on Earth, etc.).<br /><br />Aside from the stupid deviations from the book (let's face it, who's really going to read a 1500 page book?) the director used every slick gimmick you would use to get a first year community college film teacher to passionately moan "make me a complete woman." Slow motion and slanted camera angles that would have made the TV Batman director puke!<br /><br />Oh, and by the way, I have seen Plan 9 From Outer Space and it is just plain bad, it isn't "so bad it is funny" it is just bad. Still, Ed Wood didn't have the defense budget of North Korea to make his movie like they did for Battlefie
