Hm. Well, on the one hand I think multifandom authors sometimes suffer from this - they dabble in a new fandom but the stories are only superficially different cross-fandom. A multifannish version of any two guys. Not to say a mono fannish person might not suffer from the problem of creating her own characters and simply pasting on the names Illya and Napoleon. It just seems more common with dabblers (then again, maybe I'm just a harsher judge of the polyfannish butterflies *g*).

But I would also have to say that probably a lot of the writers you feel are not getting the feel and sense of the show feel that they are. :) Now, I grant the show was camp and low budget, but personally I prefer the stories that take things a little more seriously. I'd grant it isn't dead on canon, but it's canon as it could have been with more time and budget. At least, so I think. :) Then again, it's not an unreasonable argument to say a slasher cannot be a canon Nazi anyway. :)
