Psycho. Yeah, that one. For the first time ever. Yeah, it's possible to not have seen all the important and iconic movies there are out there.
Spoilers if there's somebody else in the world like me who never saw it I guess:
Well, I said before it was important and iconic... and after having seen it it's quite clear why! classic movie very well deservingly of the fame it got. The theme at the beginning made me think of Dream Theater shows of old of course
what I knew about the movie was just that there was this Norman Bates dude in a motel and the twist, so at least I could follow the story without knowing every bit. I was wondering when the motel would come into play, and I was surprised at how normal at the beginning Norman looked. And while of course - the other thing I knew - I was expecting the infamous shower scene, I didn't expect the female protagonist to die mid-film.
I think the action scenes were kinda meh - sure, it was 1960, let's cut ol' Alfred a break, but the killings and the fights really look over-staged. And I think that it was too convenient to have random officer explaining all of Norman's psyche at the end, they should have showed his interrogation. But at least I had a moment of legitimate scary surprise with the big reveal - I knew that Norman Bates was impersonating his mother, but I thought he made a puppet of her, foreshadowed by his stuffing of birds, not that he DIG OUT HER OWN ROTTING CORPSE FFS. That and Norman jumping in with the knife shortly after.... holy shit!
I can only imagine what it looked like back in the day, and I also assume there was some "scandal" for what I think at the time was considered very provoking "nudity". A great film, I'm kinda sad that it's so famous that even without seeing it I knew who Norman Bates was, but as I said at least I got some genuine surprises there.
