Noroi (2005)a found footage j-horror dealing with black magic and demonic possession, kind of like Hereditary if it was a mockumentary instead of a family drama
a journalist investigates some paranormal events involving people with psychic abilities, things get progressively more sinister as he goes deeper down the rabbit hole
found footage is usually crap and j-horror is usually crap
this one turned out to be very good despite being both at the same time
main reasons why it works
- reliance on slowly building up the atmosphere of dread through subtle details; most of the time it's just people behaving weird, legit supernatural stuff is very limited; little jump scares and no stupid SPOOKY GHOSTS
- a normal sceptic guy actively trying to solve a mystery, gathering & analyzing clues etc., which makes the story feel more 'real' and more exciting due to the twists and turns in the investigation
- goes out with a bang in super dark final sequences
all in all, a very pleasant surprise
