Plague dogs. That was the absolutely worst most depressing movie I've ever seen. It a masterwork. I don't even have people in my life I would subject them to the synopsis or "highlights" though, it's just so bleak.
Watched after Watership Down people recommend them on the same thread. Watership down is just a good story, a little heavy, but good. Plague dogs was much much more bleak then the WW2 allegory for me.
People get excited about it, post about it, and disappointed by the reality of the license in constant cycle.
It's kind of the "missing stair" problem. Those who know, can go around it, but knew people need to be informed that it's busted to avoid it until an actual solution is presented.
