I wanted to like this a lot more than I did. The pacing was set up in a way that built a solid amount of tension, yet come the end I was left feeling generally underwhelmed. It is well executed, a simple and tight story, but somewhat shallow character and concept development. The rolls that some of these talented actors portrayed translated as very casually written and lightly directed. Give it a try for a fun and relaxed sci-fi film, just don't expect anything too landmark.
