I'm torn on this one.
It certainly fits the horror genre but not quite in the way I was expecting, due to the synopsis being a tad misleading. It's quite slow paced, and I was eagerly waiting for the plot to develop in a way that it never actually did. If the synopsis had been more accurate, I might have enjoyed it more, but on the other hand, it might not have appeared intriguing enough to pick it up in the first place.
Despite the above, others have noted that the acting is superb, and they are not wrong. I had every confidence that Wil Wheaton would nail the creepy friend role, and he certainly did, plus the rest of the cast were great too.
This was an unusual little film. It was creepy and engaging but when it built up to the climax it kind of ended. It was a missed opportunity as this could of been better.
2 stars for first half which built up well.
