I ordered a copy of Ghostwatch off of eBay a few weeks back and never got around to watching it until tonight. It was good. It was really good. It was really scary, and I am a very tough customer in that regard. The ending completely blew me away.
On Halloween 1992, the BBC presented this program (or is it programme?) as a live, real story and prompted a panic like unto the broadcast of War of the Worlds in 1938. Three recognized, well-respected journalists took roles in the story. It would be like if Tom Brokaw, Greta Van Susteren, and I dunno – Geraldo Rivera, maybe, appeared as themselves in a program that was apparently real. The simple fact of their involvement lent the program instant validity.
I highly recommend the program. Go get yourself a copy ASAP. eBay and Amazon UK both have it.
