Since this is one of those places... I figured I'd lay down my two cents about the issue of Fanfiction.

Now, to be completely fair, there is such a thing as good Fanfiction. Stories that don't try to rearrange plotlines, change characters, insert impossibilities (couples, situations, etc), and that are generally interesting and well written. The unfortunate truth is that I've only ever found one of these Fanfictions, and that was a few years ago.

It's not just the fact that they are being unoriginal that bothers me, it's mostly just... everything.
1. Characters who would never, EVER get into a relationship with anyone for any reason are suddenly falling in love left and right, usually with custom characters that are supposed to represent the author.
2. Impossible plotlines are introduced into the world that was otherwise perfectly content with its own limits, or people really go for the kicker and try to twist the existing plotline into something unrecognizable. Either way, it pains me.
3. Changing other aspects about main characters already introduced in the real story. Something like, I dunno, Ishida from Bleach wearing gang clothes or something. It's just wrong.
and, of course...
4. Unoriginality. While I fully support diving into someone's world and tinkering around in an unused portion of it, most fanfictions rely heavily upon the existing plotline and characters instead of doing something innovative and daring.

Now, as I said, I know not all Fanfics are like this, but it's just the majority. And it bugs me...
