For me, all of Midsommar. I have never felt so uncomfortable (to the point of a panic attack, almost) while watching a film. On the one hand, I wanted the film to hurry up and end and on the other, I didn't want it to ever end and that is exactly what I want to feel when watching a horror/thriller and it is so rare for me to feel that uncomfortable and for that reason, that is why I wont watch it agaimn because my first and only viewing was just so perfect.
