Just so you know where I'm coming from: I've been a fan of creature features for about 50 years. Yes I'm an old fart. I also LOATHE what SciFy channel has done to the genre.
That said, I thought this was a really fun, traditional, and scary film. Yes, there are lots of things you could quibble about if you are going to take the "this wouldn't happen" trail, but if that's your schtick, go watch a documentary. I was especially pleased to see really good ACTORS like James Remar and Graham Greene in the cast. Also one of the better monsters. Even though movies about killer bears have been done to death, this has a twist that takes it beyond the cliche.
