Alot of people have never heard of it, many people compare it to more popular mangas/animes, but in my eyes, it is the best of the best. If you looked into many of the aspects of the story, like dowsing (Lyserg), you will find that most of these things exist in real life. Plus, as you read (or watch) on, there is a deeper, more complex meaning to it than just fighting and beating up a freaky snake guy(*cough*Naruto!*cough*). The English anime ruined it though, so it was not succesful in the 'States. The Japanese anime was shorter than the manga, which spans a much longer period of time. Post if you like Shaman King or know of good sites!
(I do like Naruto though)
