To get a 5 Star rating, a movie has to have everything ... good acting, storyline, etc. I can't possibly imagine anyone wanting to see this movie any other way. The 3-D adds so much more to the movie. For those who are concerned with headaches, etc that you are hearing about ... try NOT watching the 3-D without the glasses ... THAT will give you a headache.
I'm glad to see James Cameron back and I'm sure he'll provide us a sequel. The story line seemed to follow much the same as Dances With Wolves, I thought, but with a futuristic theme.
