The special effects are fantastic, especially in IMAX 3D. The story however is very simplistic and if you've seen Fern Gully or Pocahontas, there will be NO surprises at all. I had an idea of how the movie was going to end before I even sat down in the theater and Avatar basically road on rails straight to the conclusion I pictured. I wouldn't rate this with Dances with Wolves as it's often compared to, but it's a solid movie and very easy for kids to understand if you don't mind non-explicit violence and some language.
