I agree with all the reviewers before me...it must be a mandatory watch for all the school kids. My 7 year old was reluctant to go, but was in awe by the time the movie ended. I'm so glad it is a IMAX 3-D. Makes you think or rather re-think about the conflicts in our 'world'- if everyone realized how vast the universe is and how minusclue we are and at the same time how majestic and wonderful our planet is ! I have a renewed sense of appreciation for all the work done by NASA and we definitely need to take better care of our mother earth.
