The Seeding
The "unsuspecting traveler meets inbred family of cannibals in the desert" thing. But this time it's done by total idiots who think they are creating some profound artistic masterpiece. Don't bother with this one.
Club Zero
Creepy teacher starts her own cult at a posh boarding school, based on not eating. Not just eating very little, not eating at all. Weird premise that works for a while, then simply collapses under its own weight about 2/3 of the way. Tries too hard, and like the above movie, thinks too highly of itself.
The Death of Dick Long
One of those "dumb criminals doing everything wrong" type of movies. Slightly similar to the almost perfect Good Time, except set in rural Alabama rather than New York. Not as good, but still fun. A couple of truly outrageous twists along the way.
