Love John Carpenter, if for no other reason than for bringing us Halloween. Probably my favorite horror/slasher franchise of all time. So definitely don't mind him being at the top. And Romero is just a legend, so obviously. I, however, would definitely not have Raimi that high up that list. And especially not above Hitchcock and Craven. In fact, the guys I just mentioned (minus Raimi) would probably be my top 5. And Hooper definitely belongs there for the two movies mentioned. Though I have to admit, never seen any of Argento's work. Though I think I might have to definitely check some out after watching that clip.
