Movies that are most closest and similar to real life, but NOT based on a true story
The Expanse, one of my favorite Shows ever
Fargo is not a true story, though some of it was inspired by true events (wood chipper)
I got called to Minnesota to serve two years as an LDS missionary back in 2000. I absolutely loved the place. But my first day was I was stationed in Brainerd MN, and my apartment was on the edge of a frozen lake. I took a picture of it, and colored in the old brick BBQ to look like a wood chipper with feet sticking out of the top, and a large red stain across the ice, and sent it to my sister. That picture sat in her cubicle for years after that. I can’t think of that scene without thinking of it.
The Martian.
Aside from the macguffin that left Matt Damon stranded, the science was solid. Furthermore, the casual dysfunctionality and administrative infighting of the governments and agencies was brilliantly on point.
There’s one person on Mars in that film but in reality there’s zero people on Mars. That’s a really small margin of error
