Nice to know there was a theater full of morons who don’t know a thing about Batman and that his name should’ve been Dick Grayson.
Thing is, he’s not actually Dick Grayson.
At first, I even hoped he would actually be called Dick Grayson, but when you think about it, he’s not. Just because he’s the “first” Robin, that doesn’t necessarily mean that he should be called Dick Grayson.
Blake, in fact, embodies the IDEA of Robin without even having to wear a mask or costume. Listen to Blake’s story and you’ll see that he is an amalgamation of all the original Boy Wonders (with the exception of Carrie Kelly, Stephanie Brown, and Damian Wayne).
He is an orphan (like Dick and Jason Todd), he was angry and misunderstood before being mentored by Bruce (like Jason), he became a police detective (like Dick), he figured out Bruce’s identity on his own (like Tim Drake), and will presumably inherit the mantle of the Bat (like Dick).
With all these qualities, it would not be doing justice to the IDEA of Robin, and (dare I say it) the Batman mythos overall if he were only to be called Dick Grayson.
^ This guy gets it. Couldn’t have said it better myself
