I've loved Psycho since my teens, and I think it deserves to be the highest rated Hitchcock film on AFI's list given its widespread influence, but personally it's not my favorite of his films. Rear Window takes that crown, and I look forward to that Unspooled episode. BTW, kudos to Paul for mentioning Rope, such an underrated gem.
Also, with regards to Vera Miles, Twilight Zone fans may recognize her from the episode "Mirror Image".
