Saw a few obscure ones recently.
Noroi: The Curse: A Japanese documentary style found footage film about a paranormal investigator who is investigating a few seemingly unconnected incidents until he begins to discover otherwise. This move is very Japanese especially in the beginning, but it ends up being one of the best found footage movies I've seen. Great acting, eerie atmosphere and just super creepy all around. It's one of the few movies these days that manages to terrify you without cheap jump scares. This movie is not available on Netflix or Amazon, but the full movie is up on Youtube.
The Possession of Michael King: After a guy's wife dies, he vows to disprove the existence of the paranormal by trying to get himself possessed by demons. This movie tries to be found footage but suffers from the classic problem of getting the viewer to question why the character(s) would be carrying a camera around a lot of the time. This movie was ok. Possession/Exorcism movies have become rather stale and this one is a bit refreshing in not only having a male be the victim of possession instead of an innocent female, but also how the way the possession manifests makes you question at times if he's really possessed or just going crazy.
The Conspiracy: Two filmmakers set out to make a documentary about people who believe in conspiracy theories and end up getting roped into a dangerous secret society. The first half of the movie does a great job dissecting just about every conspiracy theory out there. Slowly, the filmmakers, who started out as skeptics, begin piecing things together and make a pretty significant discovery. Without trying to spoil anything, the movie then shifts to found footage format which is also done really well and is very sinister. A very intelligent and well made film.
Long Pigs: Two young filmmakers make a film about a cannibalistic serial killer who agrees to let them follow him around and document his life. If you can ignore the plausibility of a serial killer allowing his "work" to be filmed, this is actually a pretty good movie. The serial killer himself is very well acted and very convincing. Watching him slaughter, wrap, and store a human corpse in the same manner a hunter or butcher would slaughter, wrap and store a deer is something every fan of fine cinema should see. The makeup and effects in these scenes are amazing. Not for the fainthearted.
As Above, So Below: A super hot archaeologist goes to the Paris Catacombs to find a hidden chamber with an ancient relic only to find something much darker as well. I loved this one because it was part Indiana Jones, part Blair Witch and successfully accomplished capturing the best of both genres. The film also touches on Dante's Inferno in more than one part which I liked. The atmosphere is wonderful and does the job scaring the viewer. One drawback here however, is that it suffers from Shaky Cam Syndrome that many found footage movies suffer.
