Wolf's Rain is a cult classic. That is, you are either touched by it, or not. You will love it, or hate it; there is no middle ground. This show's unique premise and story will either leave a deep impact on you, or leave you confused and disappointed. Keep that in mind, before buying it.
So... what is it about? Well, If I understand correctly, this story explores the theme of the true nature/meaning of Paradise. Does it exist? What is it? What is it like? Where is it? Why search for it? The pack of wolves that spend the entirety of show's run searching for it, constantly ask themselves those questions. Should they go on, or give up? This show gets VERY philosophical at times. And what are the answers to those question? Watch Wolf's Rain to the end, and make your own conclusions. Oh, and animation is top-quality and music is by Yoko Kanno.
Alright, now let's get to the technical side. This is a Pal DVD set. Whether the show was originally recorded in this format, or NTSC, is of no importance. The video and audio are transferred beautifully, worthy of praise. Among the extras are character information, textless opening/closing and developer interviews. If you are planning on buying this particular release, you won't be disappointed. Although you might not particularly like the packaging. While not bad per sé, I think they could have come up with a better way to hold the last 6 DVD's in place.
