Damn, all my favs have been hit; Hank in the sewer, little Danny, Alan and the bugs, the carjacker and the corvair, fork in the eye, the entire The Keep, any scene with the rakoshi. The never drying paint. The hollow body.
Several (very vague) spoilers to follow.
Have to add, Nightkill and the lighter to the foot. Implant and Gina's self surgery. Deep as the Marrow and the amputated toe and the Appleton gang. Nightworld and Moki's sculpture (can not believe no one mentioned that one yet). Not so much scary, but damned good All the Rage and the 4 men locked in the conference room.
