To repeat the sage comments of jmd620 ... I HATED THIS MOVIE!
Spoiler alert and ending alert:
These are wolves that are more ugly and 5 times the size of any real wolf.
What wolves are doing living in a barren arctic wasteland is not explained.
Wolf expert tells the 7 survivors that they have to track out of the wolves area, its their only chance to survive. (This will be a laugh line in any second viewing)
No, they don't have any weapons except a few knives and two are injured.
AND ALL DIE miserable vicious deaths on the Death Trek in about 3-5 bloody days ...very visual, visceral scenes of wolves ripping the bodies apart, lot's of blood spurting out of various parts of the body.
OK ... not all are killed by the wolves ... one freezes to death, one falls from a cliff and one drowns ... in a very prolonged scene.
So what's the message?
When you're ready to be torn apart or die horribly ... think of someone you loved or remember a nice memory as they rip your arms off ... literally.
I'm serious ... that's the message each time someone dies and it shows that ... I don't have a clue ....
Hey, Stupid so-called-wolf expert ... next time stay with the wreckage and hope someone finds you.
PS When there is an interlude and the survivors talk and laugh and bond ... but never seem to understand that they have to keep looking around for Wolves! ... someone is ripped out of the group ... dragged and ... I repeat myself.
