The Sacrament (2013),
directed by Ti West.
Pretty decent found-footage movie. It's more thriller than horror. The plot is loosely based on the story of Jim Jones and "Jonestown". The first half of the movie was quite promising, then it was only disturbing.
Hagazussa (2017),
directed by Lukas Feigelfeld.
Beautiful landscapes, dark atmosphere... The movie itself is quite heavy in reception - it shows how a person who is totally isolated and excluded can be overwhelmed by paranoia and insanity. Well, it's a symbolic picture, quite "silent" (there isn't much talking). Rather for people who liked the haunting atmosphere of
The Vvitch (2015)... I personally didn't like any of them much.
Kraftidioten (2014),
directed by Hans Petter Moland.
Thanks
urgeok2 for recommending me that one. Crime drama with a hint of black comedy, quite refreshing and totally to my taste.
