I thought Avatar would be good from what I saw in the commercials.

It turned out to probably be the worst movie I ever saw. Unless you're a fan of violent movies, don't watch it. It's not worth watching the movie for three hours unless you like to see guns, explosions, and people's homes destroyed. The movie is rated PG-13 and I'm glad it is because it's very inappropriate. Bad language is in the movie, too. They wanted to originally make it ten years ago but then decided for technology to become more advanced. I rate this movie 2 1/2 stars. Post your comments below.

I have not yet seen Avatar, but from the commercials I have seen, it sounds as if you have identified some of the key components very well. When I first saw the commercials, I remember thinking that James Cameron's Avatar drew upon a lot of the same elements as James Cameron's Aliens -- the second in the Alien movie series, namely marines, companies out to exploit for the sake of money, and Sigourney Weaver.
