I saw Cherry Falls a few months ago and, it's interesting to be sure. Might not be to everyone's tastes, but it is interesting. As for others, lets see:
-Dog Soldiers (2002).
-The Burrowers (2008)-Horror/Western, which is an interesting mix of genres.
-Avenged (also known as Savaged) (2013 US films-There's an unrelated South African film of the same name that also came out that year, so avoid the confusion).
-Audition (1999)-AKA one of the most unnerving/creepy films that I've ever seen.
-House of the Devil (2009).
-Eden Lake (2008)-Has Michael Fassbender in it.
-Black Water (2007)-Australian creature feature, inspired (loosely) by true events.
-The Reef (2010)-Made by the same people, also inspired (loosely) by true events.
