I liked the film. Liam was excellent as always.
I'm glad they didn't go for the soppy Hollywood ending, that would have spoiled it for me. I loved the drama of the stand-off between Liam and the alpha at the end.
It is a bleak film overall and it doesn't really redeem itself during the story arc, but the tension and drama of the story sustain it and makes it very watchable, once you get into it.
It is unrealistic in the portrayal of wolves, but this is drama not reality. The wolves serve a function within the story and provide an ever-present threat, not to mention a few great fright moments.
Only idiots would want to kill wolves because they saw this film; the same people who want to kill a great white shark because they saw 'Jaws'. However, politically it's a bit of a bad time for the film to be released in America as grey wolves are no longer a protected species
BBC News - Congress strips grey wolf endangered species protection which will likely lead to an increase in game hunting kills.
Wolf populations worldwide:

As for the British isles, we wiped out our entire wolf populations hundreds of years ago. Although recently there has been talk of reintroducing wolves to the scottish highlands.
But putting real-world ecological issues aside, I thought the film was a good piece of entertainment, bleak but worthwhile overall.
