Well that was stupid.
"What if Batman MARRIED the Joker and ASKED to be "pushed"?"
Yeah, what if? Then you get an excuse to do whatever the heck you want with established characters, don't you?
I'm sure the authors recognized they were acting "out of character." And when you have things like Batman managing to break a steel chain because he is angry, or a bat-shaped blood splatter, it should set off your "fantastical" detector.
Maybe it's more of a meta-commentary on the roles of these two kind of characters. Yeah, they could have used any characters with a similar relationship throughout history, but they chose to use these two as a modern example of yin-yang, good-evil necessity. And they chose to explore it through the meaninglessness of terms of "good" and "evil."
I agree, the dialogue's a little rough, but I appreciate the ideas that went into it. And if that's not your thing, nbd.
