Fictional stories require a suspension of disbelief to enjoy. The more realistically you try to present your story, the harder that is. The film was shot well, and most of the actors gave pretty decent performances considering what they had to work with. Beyond that though, it was rubbish. The events were so far removed from anything even capable of happening in reality that it might as well have been about a werewolf of wendigo attack.
I don't feel pity for a character simply because they are being killed by wolves. There are far, far more humans on this planet than there are wolves. Some people, here and there, can stand to die in favor of a growing wolf population. It's especially difficult to feel any empathy when they are already scummy oil workers, some of whom are literally paid to senselessly kill wolves.
