The original writers don't understand the needs of the modern day superhero fan.By creating near-incest in the Bat family and making The Joker and Batman both feel incredibly predatory? Her rape and attack by Joker now comes across like a punishment for being sexual...which is an unexpected and gross turn of events.
DC animation doesn't understand that having edgy things happen to you doesn't make you a more developed character. Original writer hates the storyline too.
Her engaging in intercourse with Bruce allowed me to view her as human and vulnerable as anyone else. When she got shot it wasn't as surprising because I realize she isn't some stone cold hero that performs miraculous acts of valor.
Plus I don't view it as incest. I mean at first it was weird but she's an adult and she isn't his daughter.
