Well, I almost didn't watch this film. One of the beginning scenes, with grown men teasing another grown man with aphasia by tossing his thermos around and calling him a "retard", was enough to make me drop the film for bad script writing. Aside from the usual Hollywood ignorance of hypothermia, and some cardboard villains, it does have some nail-biting action scenes and stars Liam Neeson. Laurence Fishburne is in too, but he must of had a special clause in his contract. In summary, as an action film with some relatively novel scenery it's an okay watch.
