On the one hand you get a (as usual) good playing Liam Neeson, the Second truly great nature shots.
But there is one star.
Picture and sound are perfectly OK, because there is no reason for criticism.
But:
Liam's supporters remain all pretty one-dimensional and simplistic, it has problems to you, who's now deceased straight again.
Also, the story, in addition to some inconsistencies, very predictable.
Spoiler
One can predict when another will now bless from the groups for the temporal, only with the type of Versterbens there but then suddenly a surprise ... another fellow Liam is not eaten, special plunges off a cliff ...
What has, however, encouraged me the most to the point deduction, was the presentation of the wolves and the "explanation" why now a wolf pack feels compelled to masakrieren a group of poor survivor ...
This ignores a normal wolf pack in the permafrost, the bodies of a plane crash, the survivors, however, mercilessly persecuted and attack, but not to feed them, but only in order to kill them, "because people are now not even belong in this area", that is then but really difficult to digest.
The whole thing reminds very much of "Jaws Part 1 to ??" ... well, at the end of the wolves bite either in gas cylinders, nor in power cables, but in Liam Neeson, but the changes in the problem nothing more .. ,
Conclusion: If I bought the movie, I would have been about the money thrown out very angry, be held in a one-time borrowing via Amazon anger in check.
