I… really hope the new Batgirl isn’t going where I think it’s going. Because, nope. Nope, nope, nope, so much nope.
Re: Killing Joke, assuming that was a semi-serious question: Presumably for at least two reasons, one being creepy + 'it's aduuuuuult see comics r srs bsns.' The other reason is that if you remove the pointless fridge-trauma Barbara Gordon suffers, the rest of the comic is a psychodrama about Joker trying to actually communicate and reach out for help, while being Joker. The fridge bullshit is what most people think of, for good reason, but there is good Alan Moore writing as well. :/ Comics! :/
