I've never seen Grey's Anatomy. It just doesn't seem interesting to me from the previews I've seen. Just another night-time soap opera. I get my fill from GH.
Knitqueen, nope, you wouldn't have been scared. It was (sorry if I offend anyone) stupid. They made the previews look scary, but it was far from it. The dead people didn't jump up and scare you, they just sat up and started talking to each other. Each dead person in the room I mean.
