If it's not exclusive rights, fuck my shit up fam. There's no such thing as bad publicity, and hopefully, a lifetime to fix that - or if the bad show got popular, past my lifetime.
If it DOES ask for exclusive rights, hell no. I'm not giving away work so it can be remembered as the bad movie/show/videogame forever, not for a salary. That goes back to any future even though I'm not involved in it, it's not even just losing characters I love.
