The description of this product is pretty much spot on, so I won't bother explaining what it's about.
Basically, this film is quite literally the most moving thing that I've ever witnessed. It should be mandatory that everybody watches it at least once. It's depressing as hell, don't get me wrong, but it's tragically beautiful. Nearly 24 hours after watching it, I still can't stop thinking about it. I can't wait to buy it so that I can watch it over and over. It really is a stunning piece.
