Please give me your most "boring" movies!

So, I'm somewhat notorious among my friends for making them watch movies that are "weird but super boring, and impossible to stay awake during, like taking Ambien in movie format".

I always joke that I'm going to make them watch my "Boredom Trilogy" which are three of my favorite movies that even I will admit are a teensy bit slow paced, lol. They are:

and yes, I have watched them all in one night before :P

I really love horror, so any horror recs would be great. These are some other slow burn horror movies that I love but other people seem to find boring:

  • Session 9
  • The Others
  • I saw the TV Glow
  • Saint Maud
  • Infinity Pool
  • YellowBrickRoad
  • Possum
  • Crimson Peak

I also spent my last depression slump watching every long slow Merchant & Ivory-type period drama I could possibly find, so lots of people staring longingly out of windows and exchanging lingering glances full of IMPLICATIONS. I actually made a complete list of every single one I watched, because I am equally as obsessive whether I am manic or depressed, lol. So here is the list if you like that sort of thing, and if you have any more recommendations that would be GREAT, because I've kind of run out of them:

  • Howards End
  • Jane Eyre
  • Mansfield Park
  • Marie Antoinette

Thank you so much in advance for any suggestions...I've had kind of a shitty week so I told myself I can watch movies all weekend if I also make sure I clean my entire room at the same time. Wish me luck, it's pretty bad :P

Edit: Oh wow, such cool recommendations from people! I can't possibly reply to them all but please know I am just here copy-pasting names of movies into a notepad file as fast as I can so that I can watch them later, because I am a huge nerd :P Thank you so much, I am loving the suggestions! <3
