I wonder if there are any half-decent documentaries about ghosts and ghost-hunting out there on DVD? I can live without the hysteria of Most Haunted and its ilk, I'd just be interested to know if anyone can recommend any rational but open-minded documentaries which are spooky at the same time. My benchmark for this (though I haven't seen it for twenty-odd years) is the documentary Ghost Hunters that the BBC made with Peter Underwood in the mid-70s (though I daresay that will never see the light of day, and probably would be a disappointment if it did - though somewhere I still have an audio tape of the chilling recording made at a church altar during the programme, of some creepy footsteps and sighing). Have any of the paranormal societies or suchlike released anything worth seeing?
