It was great, a lot of action.

Excellent. The concept and expanding plot made it an action packed nail biter. Even some of the tremendous technological presentations were totally believable and enjoyable from start to finish and told a story in such a way that Robert Heinlein would have been proud of. When Mila Kunis told him that she loved dogs..it was precious..and a unique way of exhibiting a growing love 5 Stars thank you

Good movie. Special effects cool. I recommand.
