Psycho (1960)

So, Psycho in the 'Greatest Halloween Movies of All Time'? Let's slice it thin—like Norman Bates' sanity.

Hitchcock might as well have patented the creepy innkeeper vibe. Fans? Oh, they're just over here, casually psychoanalyzing every frame, hosting 'dress-like-your-favorite-stabbed-character' parties. If that's not top-tier Halloween material, what is?
