The Walking Dead TV series- Great show, but it was legit giving me nightmares, and I couldn’t handle the storyline once they killed Glenn off. I’m reading the comics now years later and it’s much more enjoyable
The Handmaid’s Tale TV series-- I think I got like 4 episodes in, and then they hung that one woman’s wife in front of her and sewed her vagina shut and I just couldn’t handle the graphics. I did read the book later on, though. My own imagination is just so tame compared to what they show on TV, I think
Revenge of the Sith - I was deployed to Iraq when I saw it, and was in a really bad headspace, and that scene where Anakin gets burned up and then you see them putting the Vader mask on him just really fucked me up at the time. Absolutely will never watch that one again.
