What is a Halloween Movie?

Halloween is here and television channels are flooded with Halloween movies like Hocus Pocus and Nightmare Before Christmas. However during fall break I was home watching ABC Family and Willy Wonka and the Chocolate Factory came on. Now don't get me wrong, I love that movie. Gene Wilder is one of my favorite actors, but...I would not call it a Halloween movie. It has candy...I guess that is Halloween related. ABC Family does that a lot. Harry Potter isn't really a Christmas movie either but they put all of them on during the season. I don't know ABC Family is weird.
