The Grey/YMMV


 * Artistic License Biology: The film's trailers, at least, do a very poor job of giving the impression that the writers understand real wolves, which are known to be skittish around fire and humans, whether or not they've encountered them before. It's handled better in the actual film, where it's revealed that the survivors were treading very close to the wolves' den -- the cause of most violent wolf encounters in Real Life.
 * Fridge Brilliance:
 * We never see the at the end of the film, and only get a glimpse of its aftermath after the credits. However, it's possible that the filmmakers intentionally didn't show it, because nothing they could film could possibly live up to the hype. Thus, the viewer is left to imagine how awesome it was, and come up with their own versions of it.

 * Hate Dumb: Wolfaboos are gathering like flies to boycott the movie.
 * Hell Is That Noise:.
 * The wolf calls in general but especially the Alpha's.
 * Holy Shit Quotient: Just how much worse will things get for Ottway and his companions? The ante gets upped every. Single. Time.
 * Visual Effects of Awesome / Scenery Porn: They filmed in a real wilderness in Canada and it looks beautiful. The wolves are also not CGI, but (mostly ) animatronics and puppetry, and they still look really good... and TERRIFYING.
 * Hell, the film features Sound Effects Of Awesome as well. In the theaters you will feel the power and intensity of the plane crash and your bodies will quake from the sounds of the wolves. ..
