My limits are way more about context than gore.
All the Junji Ito in the world doesn't bother me, but the part in the food fight trailer where the spaghetti has spaghetti guts hanging out legitimately upset me. The framing just reminded me too much of real bombing.
So as long as it doesn't feel, like, emotionally realistic, anything's fine. But if it reminds me of like... news footage or personal fears, that's rough, I might still watch it, but I will be spooked
And if it touches actual experiences, the most goreless version would rattle me
Any actual real footage is well out and will haunt me for years
