Psycho
Unfortunately too tired to fully watch this - in that I would occasionally nod off for seconds at a time - but I caught most of it. Hard to deny the impact that Hitchcock's Psycho had on any further presentation of psychopaths, sociopaths and the like. Hard to deny the impact that it had on this kind of filmmaking as a whole. Will definitely have to re-watch it - probably sometime this month - when I'm wide awake enough to take note of everything, including (hopefully) any foreshadowing toward what I can only conclude to be the most batshit insane ending I have seen in a while.
