One of the best documentaries I've seen Not only the best paranormal documentary I've seen but one of the best documentaries I've seen on any subject.
A fascinating and sophisticated approach to an extraordinary story, with a strange lip-syncing recreation that eerily echoes the phenomenon/possession itself. The voice both real and unreal.
The filmmakers have gone all out, creating a creepy atmosphere but also an investigative and objective style with some real pathos as well. It delves deep but I wish it was even longer.
This really is underseen and underrated (once again don't trust the IMDb ratings). It deserves a big audience.
