Another good review and this is why:

Rating: 8/10 (29 October 2011)

Thirty minutes into the movie and it'll be almost impossible not to start thinking about how it might end, like with most conspiracy theorists everyone will think they know the answer but most will be wrong.
Yes, the movie might be similar in many ways to many others because of the winter European atmosphere and the "guy against the world" feeling, but it keeps a good balance between the unrealistic things that you normally watch in an action movie and a plot that is both interesting and believable.
If you add a great leading actor and two stunning actresses to the story, it makes perfect sense that the difference between the gross and the budget is of more than 100 million dollars.
