Reads summary, sees movie, in the famous words of Arnold Schwarzenegger, "You lie!"
I know a horror movie should be suspenseful, building itself up to reveal the monster or whatever in a climax then get a good ending out of it, but to mislead their audience to do ruins the experience and feels completely cheap. It sure is much more cheaper than the movie's special affects that is for sure. The acting is awful, the main character to be completely overtaken by the "monster" is... it does not make any sense. Physically it does not make sense, but it has to be put there or else the story won't continue forward. Deus ex machina event right there to the extreme.
If I were to see the movie without reading any summary, I wouldn't be as mad as I am right now since the plot in the movie is completely different than what the summary says. They hoodwinked me, skinned me before my eyes into watching this lie of a film.
The real summary should have been like "Hunters looking for serial killer gets separated in the cold of winter and encounters something they weren't prepared for." Was that so hard to think of? And the cover art for the movie should be replaced too to avoid the lies and confusion the movie causes too. I expected skinless monsters not this crap.
TL;DR: The whole summary of the movie is a lie and the movie itself is as bad too, save yourself the time to do something else. The director of this disaster deserves to be banned from the movie business. Hell, all this lying makes them great to be a politician.
