Would you have read an else worlds spin off series about him at the end of the Dark Knight Rises where he takes up the mantle of the Bat?
My only real problem with the character was that he was was named Robin. It was a slap to the face of those of us who wanted one of the actual robins to show up. I'm fine with the idea of someone other than one of the robin's taking up the mantle and either succeeding or failing as the Batman.
It's kind of a shame we never saw that story play out.
There were still plenty of Batman villains he could have fought. Penguin, Riddler, Mad Hatter, Killer Croc, and either some version of Harley or possibly Dula Dent.
