Started watching it, but got so bored I fell asleep. What I saw was terrible. The volunteer was just a bit stressed out from what I could gather, but after his 'deliverance' he said he felt fine. The scientists measuring brain patterns etc seemed a little unconvinced that any substantial had taken place. At one point I wasn't sure if this was some kind of elaborate hoax or not. The programme before this, "The Real Exorcist" was only slightly better, although I thought was a bit open ended & was full of examples of "their word against ours". Quite disappointing all round really!
