You know exactly what these are. You’ll watch something so good, so devastating, so personal to you that you think it’s amazing, but you’re never going to put yourself through that again in your life. My wife calls these movies “shelfers”, because for some reason she’ll buy them, leave them IN the shrink wrap, put them on the shelf and never touch them again. I get it. Something that impacted you to that degree should be part of your collection and the shrink wrap is simply there to stop you, should you ever be so dumb, and give you a minute or so to remember what it did to you the first time before you make the mistake of trying to repeat view.
The common theme on my list is the horror of real life. Drug addiction, racism, terrorism, genocide and unspeakable acts. The movies are powerful, outstanding and ones I think people should see. That being said, I’m not exactly recommending them. They did, after all, mess me up so badly I never want to see them again, but I’d rate any movie on this list a 10/10.
