Like people are saying in the other thread, all the extra Babs stuff isn't good at all. And shouldn't of been added at all.
I haven't notice anyone talk about this yet. There's a mid credit sequence that has a now paralysed Barbara coming home and opening a secret room with a bunch of computers, and the scene ends with her becoming Oracle.
Which i think if you that and the short film before (the first 28:05) ultimately changes the focus killing joke to become a Barbara story, instead of the relationship between Batman and Joker.
