My girlfriend has a problem with suspension of disbelief so she doesn't like sci-fi. She loved this movie. I have always viewed movies as entertainment (not real life) so it is easy for me to suspend disbelief. In my opinion, Avatar is the best movie ever made. The story and effects are terrific and the 3D is a bonus - it totally immerses you into the story. If you haven't seen it in Imax 3D, go back and see it again at a good venue.
