Not too badly done cliche werewolf movie, a bit half-assed on the rest. Just pretty much goes through all the classic steps. The "Viking" thing is just bait.

Wolf looks a bit shabby, but the transformation scene is ok.

Timeline is blurry, there seem to be nights, so it does not happen on a 2-3 days scale, however the moon is full and nothing suggests that a whole month passed between events either.

The relationship between the mother and daughter is really like "yeah let's just say they have history" for the sake of it. Nothing comes out of it.

Stupid things:
- the girl just disappears from home for two whole days and it seems no one noticed ?
- the shittiest werewolf hunter ever. The guy know how to do it, yet instead he just [spoiler]try to ran her with a car, easily (and obviously missing her) while at the same time hurting two people and killing himself[/spoiler] which such an obvious result for such a lame action.

Ending is a bit weird too. It's not shown whether she [spoiler]kills Thane. But the silver bullet left might suggest she didn't.[/spoiler] However, her hand looks healed in the final scene, so it's at the very least weeks after. So does she just go around with that bullet on her every day ?
