This movie was basically a great premise and would only work if it was short and fast paced in order to prevent it from just going on and on and becoming to talky. This movie completely did what was necessary to keep it great. There was no slow build. It jumped right into the story and kept its foot on the gas for the 90 minute run time. It's very smart and has crazy philosophical/scientific ramifications. The action was different and intense. And the movie overall seemed to be very fresh and edgy.
I'd definitely recommend people checking this movie out. It was a very fun and quick watch that had a great premise and didn't drop the ball.
