Thanks for the review and I really enjoyed this film.
In regards to the wolves being aggressive, nobody seems to remember that this behavior was explained early in the film, shortly after the plane crashed. Liam's character tells the others that wolves are territorial, and that they will become aggressive when an animal (or human) is within a certain distance of their den. He gives a specific radius of distance, but I don't remember exactly what it was. In any case, it turns out that they were moving towards the den as they travelled, which explains why more wolves appeared and why they became more aggressive. I didn't really want to steer the topic back in this direction, but I read too many comments in this thread about how the wolves' behavior was unrealistic, or unexplained. I hope this helps clear that up a bit.
On a different note, I agree with some other posters here that the film was much deeper than a survival story. It is very existential in its theme, and provides the opportunity for quite a bit of reflection and discussion, if you give it that opportunity. I contend that it is closer to an art house film than a mainstream Hollywood movie, but Liam Neeson's presence gave it more commercial appeal and so a lot of people hoping for "Taken" meets "The Edge" were disappointed.
