Really? Writing it seems much easier to me most of the time

I can't write to save my life.

fanfiction can range from fun to silly/bad the silly and bad types tending to be Kingdom Hearts (which has a very venomous fanbase) or some anime. In addition a lot of fanfics tend to stray away from the original source material and go into some sort of horrendous creep fest

Best fan fics stay within the realms of the canon and yet is still new and fresh in a good way
