I gave the movie 5 stars because it will definitely will immerse you in the story. However if you are looking for the IMAX 3D version to pull you out of your seat and blow you away you will be a little disappointed. Certain parts of the movie were enhanced by the effects, but there simply weren't enough. Most IMAX 3D features take your breath away and pull you in the film. The effects in this film did not. Seems like they missed a golden opportunity in 3D here.
The 2 hour and 40 minutes fly by. The story kept moving along and the special effects/GCI only enhanced the film and never took away from it.
