I hated the very premise. It doesn't matter to me how well they did or didn't deal with it (though I do think they did it in the only way they could have), because every second of it felt like the kind of fanfic I run screaming from. I never liked Dawn on BtVS, either. They worked her into the show very creatively, but I still resented the disruption of her introduction. (And this is with having missed the entire season she was introduced in. I suspect that if I'd actually seen her debut, I would have been even more annoyed.) If they'd tried on SPN to pull a Dawn with whats-his-face, I would have seriously reconsidered my already-slowly-waning attachment to the show.

And don't even get me started on the fresh material for the John-haters. Ugh.
