Saw Dark Nature in a busy Glasgow cinema too and enjoyed it. It has a good balance of Hitchcockian suspense and psychotronic-style death scenes i.e. close-ups of axes in heads; humorous expressions of shock on actors' faces. Some nods to Herschell Gordon Lewis in there too maybe. Yes, you can tell it was made on a small budget and the acting at times was a little bit suspect but the location is stunning and adds a lot to the atmosphere of the movie, which is the point I guess considering its title. Some nice music included in it too. As mentioned in one of the other posts, the use of the bear trap could possibly be the finest in cinema history.
