Wednesady nights. Same time as lost. I just DVR it and catch it later. Good stuff, they'll catch evidence, and do whatever it takes to disprove it, so it's more believeable that the hunters that use psychics.
As far as movies, the RING is awesome, and Ringu, the original japanese is great stuff too. No one mentioned Suspiria, an old italian movie that was creepy as hell. . .never got past the first few minutes of it. Great stuff. Also, when I was a kid, the original Nightmare on Elm street gave me nightmares for weeks.
