Heisei Tanuki Gassen Ponpoko - From Studio Ghibli - I saw it at the local anime fan gathering. It's about a bunch of Tanuki (transforming racoon creatures from Japanese myth), who are trying to save their area from development by humans. They struggle very so very hard and for a moment it looks like they might have won, but their home is wiped out anyway and they hold this parade of various ghostly figures singing and dancing until they faded out. It was heartbreaking, they'd fought so hard and they they were going off to die, fading out and they were celebrating while doing it. It was the celebrating that really got to me. I just had to go into the bathroom and broke down. It was one of the sadest things I've ever seen. I was watching it in japanese, so I may have misunderstood what was going on, but it was just heartbreaking to watch.
