I really don't get this at all. Robin didn't show up until Batman's third year. TDK takes place during what, the end of Batman's first year? Maybe the beginning of the second? There are countless year one/year two stories that don't involve Robin (hell, Robin wasn't even introduced in Legends of the Dark Knight until the 100th issue). By the time Robin had showed up in the comics post crisis the Joker, Catwoman, Penguin, Riddler, Two Face, Mad Hatter, Calendar Man, Hugo Strange and countless other villains had already been introduced. So please, someone explain to me how Nolan is ignoring years of comic book history by ignoring a character that logically shouldn't even show up until a good year and a half to two years after TDK even takes place. He's not ignoring anything, he's just acknowledging something that apparently a lot of people don't want to accept: Batman was solo for quite a bit of time and a lot of other characters were introduced before Dick Grayson's parents were even killed.
