I was pleasantly surprised, as I had expected a rather mediocre action movie, but instead I was presented with a pretty good action-thriller. The film was very good at keeping you guessing as to the perpetrator's identity, and I found myself guessing quite a bit. There were some silly scenes however, and the film was rife with "movie-science", but overall I was pleased. If you like Liam Neeson movies, then you'll like this, as the film is similar to his other films. Overall, I'd give it a 7/10.
