The story is good, I'm not keen on the art, but I'm buying the books to support the license and the title. I've never been much for manga/anime but it's always been my own personal take on it. All my friends love it, though.
I am eagerly awaiting the Dark Crystal books, too! The art, that I've seen, is awesome there--looks like the characters from the movie for sure. I hope the story will be as good.
