Wow, what a ride! Why this show was cancelled after it's first season is beyond me. It is one of the most original shows I have seen in a very long time. My first reaction upon watching it was that how can they make 50 different versions of the same day interesting, but they pulled it off. In fact sometimes I forgot It was the same day repeating. Every new version of the day has new clues to the puzzle, making every episode just as exciting. The only negative thing to say about the story is that not everything is explained and there are a few loose threads that are never explained.
The acting is top notch across the board and the attention to detail is superb. It must have been an impossible job too film so many versions of the same situations, but they pulled it off. My head hurts just thinking how it must have been writing the screenplay and connecting all the dots. If you ever get a chance to watch Day Break take it. 9/10
