I am not a person who goes to see a movie more than once, but I am planning on seeing this again. IMAX 3D is a must. I very rarely get emotional in a film, but did about 5 times during this one. If they could have changed why we were there, I think that the story would have been a little better. As it was, I really didn't care why humans were there. The rest of the story overshadows that insignificant fact. I think that this is quite possibly the best film I have seen in a very long time. I hope that they can continue the story in sequels. There is many different ways they could continue this.
