My problem with Robin (it's not her gender)
The problem I have with Carrie/Robin is that we practically know nothing about her. She is just some girl Batman saved from a mugging and apparently she admired that so much she decided to become his new sidekick. That’s it.
Does she have a family? How would her parents feel about her taking up an illegal vigilante hobby that involves risking her life on a daily basis? And what kind of an @$$hole is Batman for not asking those questions himself? How irresponsible is it of him to take on a 13 year old girl as a sidekick at all? Even if she was a miserable orphan with nothing to lose that would be totally unacceptable. If Batman took my child under his wing just like that, no questions asked, I would be freaking pi§§ed! (Not that I could do much about it – he is Batman, after all. Would you pick a fight with him?)
On the other hand one can argue that we should be grateful that we get spared yet another run-off-the-mill origin story with her. We’ve seen those before and they’re all essentially the same anyway. I get it. Nevertheless, this leaves her a very flat, weird character.
That all being said, I absolutely love both the comic book and the movie(s).
Cheers
