I watched this third one, imo. they shouldn't have kept the same cast members for the lead roles. It was totally pointless and it kind of broke the mood.
That was my original fault, I didn't mind much after a while, but at first it really put me off watching (especially as in terms of role acting, they still seemed to be playing their 20th century characters and seemed very out of place). I thought it was kind of a weak choice, since IMO this franchise is very stylish and can very easily survive without them.
However, after a bit you can over come this I think, as said the movie is very stylistic and as far as werewolve movies goes is very modern and one of the better ones (
Dog Soldiers it is not however). Visually this is a ripoff of
Ravenous, but this is probably due to similar setting and the monolithic view everyone has of the "pioneer days". It is a highly enjoyable movie, you overcome the greivances with the casting and the Tremors 4 style "actor playing relatives of their modern character" but unfortunately, a lot of the themes in the characters is also the same as in the first movie so that does spark deja vu. However, since the subject is somewhat different, with the whole ancient evil feel, the movie is very much different to the others, and the werewolves are in their element in a seige.
Recommended viewing, as long as you watch the first 2 first.
