I’m far from the first to feel this way about it, but Requiem for a Dream. I was already not interested in hard drug use before the film, but after, I understand just why you never go near it.

Grave of the Fireflies

"In Fabric" 2018

Star Wars. Dad took us 3 kids to see it in the back of our station wagon at a drive in during the orignial release, Reversed in, tailgate down and watched it. Haven't seen it since. No desire too. Im 58.

Salo, or the 120 Days of Sodom

truely disgusting, made me want to vomit, but damn if it didnt teach me more about the human experience, empathy, perspective and love

edit: im gonna add more as i think of them.

Full Metal Jacket

first watched this while on acid, the first half scared me pretty immensely. i have always been anti authority, but watching this and seeing such pure voluntary subjugation really hurt, to me its about more than war (obviously), its about human struggle and an understanding of why we do the things we do.

Primer. It's a movie about time travel, and it's absolutely amazingly done. But it's also mind-bending and not that exciting.

Breakfast Club. I saw it in the 80s, and loved it, but thought I'd never watch it again. I put it on again during COVID and while it still holds up, I definitely won't watch it a third time. Past is prologue, and all.

The matrix

Waltz with Bashir or Taxidermia

Amour was quite challenging.

Wind River
