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.
It's not just you, it's much safer to read disturbing content than watch it on TV, it has something to do with how your mind forms memories. I think while reading your mind will on some level make up pictures to go with it, but only has access to the libraries of what you can already imagine. So if you have nightmares about it later or whatever it can still be challenging, but it's hard to get as traumatised as you can by seeing images on TV/film or irl.
My source for this is something my wife read while we were researching ways to help our little girl, who gets freaked out by certain things on TV very easily. It seems to hold true for her at least.
I also stopped there. I may be misremembering because of trauma but when he said 'Maggie I'll find you' it destroyed me. In his last moments all he could think about was his wife, I felt that on a deep personal level.
I also remember crying when Beth died. That scene where Daryl carries her out was just too much. And then I remember they had the actress on that show they always had right after called Talking Dead and she ended up crying because her character was dead and then like everyone on that stage was crying.
