The scenes in this movie were so real at no point did I think I was watching CGI. They are way beyond what you expect from the trailers. Some plot lines were predictable but you didn't know how they were going to achieve them so it was still enjoyable to watch. There are scenes of death and loss that elicit an emotional response but it's not excessive and blends in well with the rest of the story. Going to see it at the IMAX in 3D was definitely the right choice. At one point I actually tried to blow away a bug from the movie that was floating in front of my face. I never felt the need to look at my watch even though with previews you're in your seat for three hours. Everyone needs to see it this way at least once.
