The first two Evil Dead's are mandatory. The rest of the viewing usually depends on whom I am with and what their tastes are--Friday the 13th marathons are not uncommon, last year I did a Childs Play marathon, and this year it looks like a Sleepaway Camp marathon might be in the works; I usually try to squeeze in Romero's Dead trilogy and the Exorcist if I can. Problem is I watch a lot of horror films regularly so Halloween viewing is not that special--I usually end up watching the cheesy stuff like Sleepaway Camp that I would never watch any other time.

Oh, and lets not forget The Simpsons Halloween Special.
