I honestly think that this original version, despite it being black and white, is much better than the newer version. And did you hear? Apparently they're making a prologue movie based on this called "Bates Motel." I just hope it'll be any good... But that smile is so creepy... I LIKE IT! That shows very good acing right there.
That final scene scared the shit out of me...I've been watching some documentaries about multiple personality disorder and it looks like Psycho portrays it pretty accurately. It's a terrifying and fascinating condition.
