Ghost shows are the closest I can get to horror movies. I love them, but most of them are so much playing to the network camera and so little actual investigating. One of my biggest bones was best exemplified by an episode of Ghost Hunters International where the "ghost" turned off "all the electronics"...except the network cameras. Which didn't seem to bother this supposedly electronic hating ghost who force shut off everything else before communicating. Really guys? REALLY? I don't even know, seriously.
That's not to say I don't believe in ghosts or that I think all the shows are bogus, because I really do think there are legitimate cases, but the network doesn't want reality, it wants ratings.
