To say it's a perversion is very closed minded. It's an expansion, nothing more, nothing else. How it's written and the quality within has nothing to do with the fact that the characters are borrowed.

Some of the fanfic writers out there blow the established, "professional" authors I read out of the water. They work with words better, weave visuals better, everything. And to say that it's easier than normal fiction is bullshit, too. Sometimes it's HARDER to work with other people's characters. You have to work around canon without getting rid of it, find the remeaning plot threads in the ones that already exist.

To me, it is fabulous practice for young (and even older) writers, and...to be perfectly frank, there's a reason I sit at the computer all the time, and read certain stories over and over again. Some of it has to do with loving the characters. But if it was all worthless crap like a lot of it is, I wouldn't even bother.

Personally, it sounds to me like he's a bit of a snob. He probably thinks there's no merit in comic books or manga, either...
