I love sci fi and animation but am usually reluctant to see hyped movies. I was also concerned about the 3-D headache factor. But I forced my family to go with me and we were all very glad we went. The story is not especially original, but the 3D was fantastic - you felt drawn in to the story. Great tech work plus a good story (if only ...) and no headache, only the wish that all movies could be in 3D.
