Haven't seen Bad Blood yet, I imagine it's terrible, but she didn't really get any characterisation at all in Son of Batman aprt from "wants to sex Bruce" and "sort of cares for Damian".  That's... literally it. Nothing about her commitment to the League's teachings, nothing about her resentment of her father, nothing about her wish to keep Damian with her. Given that she can be a very interesting character if used well, it's just another one of the movie's many sins.
