I'll bring this one up while its on my mind. Anyone seen this series? You think WSD or Plague Dogs is sad...try to watch the last episode of the series without crying. You care too much by the end.
Anyway, I'm trying not to spoil it. I figure the series is set in the future, and outside of cities, a lot of surrounding areas are wastelands, and only the wealthy have true safety and security. Nobody can find "paradise" in these conditions, thus it is, wolves take on a journey hoping to unlock paradise for all again. Most humans believe its just a story, a myth, and that there is no hope for paradise. If you manage to watch the entire series (and you have to watch one after the other or lose the storyline) it makes you think about the world as a whole. You'll be asking yourself what really paradise is, and if paradise can exist. Pretty deep for a tv series.
The animation is hand drawn, and this was created before CGI really took off. I like the music and it fits. Its one of the only anime series I've bothered to sit down and watch. I've seen episodes on youtube in English; I found an old fansub years ago on some download site that is pretty close to the English version on youtube. Its not cheap to purchase which is terribly unfortunate (but standard practice for Japanese media).
