Similar to The Witch in that it's horror but Midsommar, definitely a one and done for me! I would add pretty much anything by Lars Von Trier, I can't even get through many of his films once tbh! I was impressed with Breaking the Waves but it was an immediate one and done. I have seen Room more than once, in pieces anyway, I think it's handled so well that I can deal with it. I find the part after she escapes the most emotional. I have no desire to watch Marriage Story, it just looks so bleak. I would place Blue Valentine and Take This Waltz in that same category of the death of love type films that make you want to never watch them again lol! Great read!
