That was certainly an issue in A Good And Happy Child. But don't you think that The Exorcist (and its sequels/prequels) and The Exorcism of Emily Rose come down pretty firmly on the side of "it's a demon"? The Last Exorcism is definitely "or maybe it is you who are the crazy." Or are you also including exorcism in books (which I don't know much about). Yeah, I think part of what makes Noroi work so well is that it's taking place in a culture where there are TV shows looking for child psychics and communal rituals still take places in the back woods.
I don't know if you watch Destination Truth, but I like it for similar reasons. There's one episode where they go to investigate ghosts at a Buddhist cemetery in Thailand, and their translator dude has already told them the signs that ghosts are around = the smell of corpses, and dogs barking (I've heard the dogs barking one myself, in Indonesia). So they're sitting there in the dark waiting for ghosts in the cemetery, and hear dogs barking and smell something bad, and soon the translator is gone. High-tailed it out of there. They find him the next day and he's like "yeah, F the shit you're doing."
