So I see so many people complaining about the way this movie ends. I didn't see the extra scene but was completely satisfied with the ending. I think this movie is wonderful from beginning to end. The action is fairly non-stop, there are several times when I was jumping out of my seat. Yet today the next day I can't stop thinking about it. I think for me I started looking for more meaning around the middle, and I think the wolves represent the main characters depression and in the end he decides to stop running from fear and sadness and fight. The other interpretation I thought of was that he dies early on and is in hell for most of the movie. I don't know for sure which the true interpretation is or even if I'm completely off, but thinking about the movie in these terms is really satisfying for me.
I think ultimately if all you take away from this movie is the suspense and action that you have missed a significant part. To the person who was falling asleep.....really? just really? I found the movie riveting and would recommend it to anyone who can handle a decent amount of gore and still look past the action to possible other interpretations.
