I really wanted to like this movie more than I did. The idea of the movie is very cool. A time machine that keeps resetting time when you die. Cool idea right? It is, but after the 4th or 5th time it started getting repetitive. I feel the roll for Renton was not cast correctly. Renton has the look of a tough guy but plays an engineer. I really like end of world movies, or close it. This one just didn't do it for me.
