Colin Farrell is an interesting person: an actor who is both good and overrated at the same time. Considering that most young actors his age are practically painful to watch, seeing Farrell display a range of emotions through his facial expression is refreshing and reassuring. He's not great, however; many people tend to gush about him a bit much. He's still young, and although he is good, it doesn't seem that he's gotten over that "I'm trying so hard and it will break my heart if people don't like me even though I pretend I don't care what people think" attitude yet. I guess that's not his fault, since he isn't as experienced as other actors yet; it's just that some people say he's going to be the next great leading man, and I say: wait. I think he has the potential to be, but only time will tell.
Also, I have to talk about the film's ending. So, this is the *SPOILER* warning here.
I was very put off by the ending. This trend in Hollywood to have bad guys never receive retribution bothers me. In fact, in many popular films now we're expected to sympathize with robbers and thieves, who are often leading characters. Farrells character is by no means a good guy, but Sutherland should not have gotten away. He had no right to do what he did. I just had to say something about that.
Aside from that, the film is adequate. They didn't do as well as they could have with the premise, so I would say it's an average film.
