The logic of the plot does not stand to much scrutiny, and yet, I was very much entertained. The story is not nearly as far fetched, compared to other time travel novies, as some viewers complain about. I actually like the premise and was surprised by the storys emotional core, which gives way to some solid performances - especially by Yvonne S. The effects are also very convincing. Overall a great action movie with an interesting story and likable characters.
