It's stylish, has a pretty unique concept and solid pacing, so it keeps you engaged throughout. However, you need to stretch your willing suspension of disbelief wide enough to drive a truck through, since many of the plot points are maddeningly unrealistic, even by sci-fi standards. Most of the characters are dislikeable, and some of the performances felt a little stiff, but overall there weren't too many shortcomings due to the lack of budget. It's an entertaining enough film if you don't ask too much of it.
