I wouldn't take it all that seriously. The programme in question is a hilarious mess of psychics, mediums, glowing orbs and Yvette Fielding looking shit scared in infra-red. All these elements are guaranteed in every show!

The last of the 3 shows is on tonight, so if they're going to dig up the Llanbedr Stones, it'll be between 9 and 10pm. I think I might just tune in (I love it when Yvette looks like she's about to wee herself).
