Why is Japanese material so special?

Tell me, because I do not know. Their people are not so admirable, and their actual political position in the world is admirable either. I get the acute feeling somehow from seeing how in many websites, that they set aside a section for "anime" like in warez sites, fanfiction sites, and so on. Perhaps that is all fandom stuff, warez included. If that is so, then what is the explanation for all of this popularity of Japanese material? Why not Mexican? Or German? Or Swedish? Is there any part of their production of cartoons that makes it far superior to anything else? I feel that it does. I really hate American cartoons. I do not feel that American cartoons have anything to them. So what is this difference?

Perhaps you may not know the answer as well, and that is fine. But perhaps you may have some idea on the answer, which you could tell.

I'm not over-analyzing, because I hate American culture as it stands. I know something is wrong with it with all its reality shows and bad sitcoms, but there must be something underlaying it that is the problem. Knowing the problem is at least important for personal satisfaction.
