I was really looking forward to this movie but it was a disappointment. The computer generated graphics were outstanding, but the story line was tired and predictable. The evil mining corporation, the evil military - all been told before many many times. The sections about the native people were very interesting but in the end, a predictable movie. Also, no reason for it to be PG-13 - the language and extra violence didn't add anything. Edit that stuff out and make it PG. Won't hurt an already average movie.
