Hocus Pocus is my favorite Halloween movie to this day. I love Casper, NMBC, and Sleepy Hollow (both the Burton flick and the animated version). And I haven't seen The Halloween That Almost Wasn't listed in here yet. It's an absolute cheese fest and I frickin' love it. Oh and The Worst Witch! Tim Curry's song is magical.
EDIT: And I almost forgot Wallace & Gromit: Curse of the Were-Rabbit. It's definitely not from my childhood, but if I ever have kids, I will make it part of theirs.
