| Villmark (2003) |  |
aka Dark Woods
5 people go to a norwegian wood (yep, it's a scandinavian film) to camp in a remote located cabin, and there is a pond nearby....I liked the movie for its threatening and mysterious atmosphere, which starts to built up after some time. But also for those kinda raw and "amateurish" looking style. And unlike a lot of other movies in its final act it even can add onto with tension and being a bit of eerie. Rather minimalistic and limited budget done right.
