Probably no one would have anticipated it, this is a surprise movie, especially being an anti-Christmas theme. Possibly the one last time I enjoyed was a Finnish film called 'Rare Export', that's the name came in my mind after watching this. I also could not believe this rated PG13, well it differs in other countries. Of course, there are plenty of intensified frightening scenes, even for the adults, but no gores. The violence parts were well edited/shot, yet it makes sure they're still part of the story without showing them. I think it was a smart film... read the rest.
