One thing here that makes me shudder: Giving a captive subject a megadose of acid and playing "your mother hates you" thousands of times. I really hope that didn't really happen.
This is what makes MK Ultra brilliant from a story-telling point of view. Paranoid scientists thrown from windows by silent, shadowy men keeping the nation's secrets. Lunatics tied to beds with evil football helmets torturing them to unwillingly benefit the nation's security.
I mean, completely batshit insane and the men in black decide to experiment on you. Nice. Living hell, some would say.
