Can't figure out why, in the theme song, they say "We're D.C. Superhero girls!"...
I mean... does Harry Potter ever say: "I'm a WB wizard!", or Punisher: "I'm a Netflix vigilante!"?
No. No they did not. Because a character referencing the fact that they're actually just a character is the antithesis of the objective of cinematic storytelling, is jarring, & just plain weird.
