Short and interesting. This looks at the true story behind The Exorcist. It looks at most of the issues evenhandedly. A number of people from catholics, scientists etc. give their opinions. It looks at the psychology of a child, but never in detail. It certainly tries to sway you toward believing the supernatural, with the ominous voice over and creepy music. But had it been totally neutral, then it wouldn't have been as entertaining. I was kind of disappointed in the recreations. Even slightly cheesy ones can be creepy, and I love documentaries like this, as they can always scare you a bit. This failed to create any fear though.
