I’ll get the ball rolling:
Dead Man’s Shoe (2004)
Sounds like a tearjerking tale of a recently-bereaved man returning the shoe of a road accident victim he found in a bush to the victim’s late wife, through which they spark a deep friendship that goes beyond mere love. PG-13 5/10 Oscar-bait shite.
War of the World. It’s a sad and long documentary about how and why we wage war with one another.
