They Are Here: The Real World of the Poltergeists (2007)

This two-parter is about as insightful and plausible as one of those "Histories Mysteries" specials, or that weekly John Edwards "Coast to Coast" baloney. A stream of real-life spook experts, ghost story writers and scientist types are interviewed. They try to convince (usually with little real proof) of the existence of the kind of paranormal activity seen in 'Poltergeist.'
