The biggest problem with Noroi is that it doesn't look like a real documentary / found footage at all. The music ruins the immersion and in some places you can see that there were multiple takes. Immersion is the whole point of the subgenre and the lack of it made not scary and annoying. The Hori character is interesting to redeem the movie somewhat. Noroi had good buildup, a sense of mystery but the ending was cliche.
