As someone who spend more than their share in the service, the joke always floated around about replacing us with "robots". The movie explores that option but still shows that flaws that can come from using it. I think the actors in this movie did a great job and I was glued to the set the whole time. The previews had me believing that it was very basic in plot, as far as the rogue unmanned ship was concerned, but there was actually a lot more to it. Some good twists and turns for sure, and lots of action that takes you all over the globe! I really enjoyed the movie, it was well done and the technological toys that are shown give it a good backdrop as to what it "might" be in the future.
