I'd say that Birds of Prey was more of a team movie than the first X-Men or Guardians of the Galaxy, at least in the sense of giving the non-lead team members a chance to shine. Black Canary got a real character arc.
I do think it should have been titled "Harley Quinn: #MeToo". Because that would tell much more on what the movie was, and would have been a giant fuck you to all the misogynist haters on Youtube.
