This movie was the best animated movie I have ever seen! Hands down. I've seen it in all 3 venues-- Regular, 3D and Imax 3D and each one was better than the other. I wasnt really big on a technologically advanced military going up against people without the same technology however, they did mix it up really well and I really enjoyed this movie! I absolutely recommend it. Keep in mind it is a long movie though and Imax 3D is extremely popular and almost always sold out except for the late show which starts around 10:30 pm. that puts you in at around 2am......... Plan ahead for Imax 3D
