I feel like my expectations may have been a little high going into this one. From what I knew about this movie it sounded like it was going to be a horror/psychological thriller, but it felt more like a campy comedy with a few deaths. I'll try not to put in any major spoilers.
A group of American friends decide to go to a Swedish culture festival. Due to numerous misunderstandings from the cultural differences along with some potent tea, (which does add some nice visual touches) hilarity ensues. There is tension as the friends argue among themselves. But, as the movie progresses they gradually become less worried about their problems back home and find themselves completely absorbed in this new world that is almost literally to die for.
