Anyway, a little while ago I decided I hated myself and watched 3 of the most depressing animated(and possibly all) movies that exist: The Plague Dogs, which a couple scenes can be found in my signature. Where The Wind Blows, and Grave of The Fireflies.
Two of these movies are about the apocalypse.
Where the Wind Blows: A movie about a quirky, British retiree couple. And them going through Nuclear War and convinced until the end that the government, who they have unquestionably obeyed, will rescue them. Until they slowly die of radiaton poisoning and end with them praying for death. Did I mention that they think it is just like the Blitz and are increasingly confused that there is no television or mail, at the same time it shows that they are exposed to fallout.
Grave of The Fireflies: Anime about two lovable children caught in Hiroshima. There mother dies in the blast, and they eventually starve to death. Not much more you can say about that.
Now, what's your apocalypse movie? Famous, obscure, good, bad. All types! Maybe leave a plot description like what I did.
I look forward to reading about them.
