DO NOT see this movie unless you enjoy disturbing scenes.
3.5 hours is too long for any movie, if you're going to see this movie I recommend you leave after intermission. We would have saved ourselves the ultra disturbing scenes, and also The plot doesn't really go anywhere after that, So leaving in the middle doesn't affect the ending.
One of my friends walked out as did several other people.
If you are in any way sensitive to disturbing content please Don't see this or The Substance. I DEEPLY regretted seeing both these movies. You cannot unsee stuff after you already been subjected to it on screen. It's awful.
