I loved the IMAX 3D. It felt like you were in the movie. However, I think some parts of the movie, like the horse chase, were really only there to show off the IMAX 3D technology. I also felt that it could be scary for kids (especially in the IMAX 3D). The horse chase with the black horses and red eyes is scary for me! And the scenes with the ghost of Christmas future are pretty scary too. All and all though I loved it.
