It had a really great premise but was not as good as it could have been. There were too many cliched lines and the situations seemed too familiar despite the creative premise. It was just too simple - too familiar. Watching the Costner character gain a conscience was interesting but seemed too simply done. More philosophical discussion or maybe hearing Costner's complex thoughts - better.

Good movie, interesting premise. It definitely kept us on the edges of our seats. I loved the change in Kevin Costner's character over the course of the movie, and I smelled sequel all over the ending. It was extremely violent, more so that was necessary, in my opinion. Thanks for the opportunity to see it early.

It was a bit gruesome in some parts but overall it was a great movie.

It was clever, funny, unrealistic yet found a way to entice the viewer yo keep watching. Kudos to Costner !
