This is another low budget science fiction, but is a bit better than most that suffer from a similar budget because the acting is better in this one, not fantastic, but better than the average B movie. Where it fails is more in the writing and directing. Not that they are bad, but the writing is pretty much predictable with only a couple (not so) surprises in store. You can see things coming before they happen. The directing was less imaginative that it could have been also. But then, it's easy to pick it apart after the fact, so perhaps, instead, just simply watch it for what it is, a werewolf movie. It is fairly enjoyable. I have it rated a 3, but it a just little better, say 3.5, because Amazons 3 means "it's okay" which to me means, I could take it or leave it. It's a little better than that. In other words I'm not sorry I watched it and while I wouldn't say I "liked" , which is what the 4 rating is, I would say it's worth 1 watch, and I might watch it again someday. But liked means, to me, I'll remember it for some time, and I don't think it's memorable. A 5 star movie is one I will remember at least parts of for long term. I wish Amazon had a 1-10 rating system.
Isabella Calthorpe stars as Sarah, who returns home to England for a visit after a long absence. We get to meet all the siblings and other guest who are all pretty much party animals, animals is operative with some, and move to the party. Then, of course the predictable storm, power outage, lack of phone service and so on. After the party moves to the main house, we meet the beast. There is a secret soon to be revealed, but I bet you can, GASP, guess what it is without much thought, or seeing the film. Still has some fairly good scenes and the cast does a good job executing their respective roles.
The creature effects were not bad, not great, but not bad. I (and I expect you) have seen much worse. Would I recommend it, yes either rented or bought cheap, say < five bucks shipped.
