I would be very dissapointed if Robin was in it. Well first of all, let me express my feelings on the character. I got into Batman in '88. If one remembers or knows, there was no Robin by then and the Batman stories were one off detective stories, with lone Batman solving the cases and confronting the perpetrators at the end. I was aware of Robin and of course, Jason's costume was on display in the batcave all the time and there were many moments when Batman was looking at it, but my point is that the Batman I got to know and love was the very dark, lone character solving often supernatural and/or horrorish stories. The dark Burton movies followed the suit of the lone and dark Batman. When Tim Drake appeared, he was awesome and is still one of my favorite characters (loved the first Robin comic series), but he was staying in the cave workin on the computer and then even when he became Robin, there were plenty of lone Batman issues anyway and they werent such strong team that went together everywhere like the previous Robins
So MY Batman, the Batman I got to know, was a lone figure and thats the Batman that got me in and that Im a fan of. Having anyone besides him would completely change everything. He wouldnt have those monologues or deep lone thoughts, the entire character wouldve been presented in such a radically different ways. When he was alone, he was constantly thinking and wondering, you realy got into his head and you felt like its you and him. With Robin around , naturally its all different because he now has someone to talk to and someone on his side all the time
Another thing is that I cant imagine Robin fitting in a more realistic universe at all. We're talking about a kid here, I dont think Bale's Batman (or Keaton's either) would under any circumstances agree to work with a skilled kid and agreed to have him on his side fighting crime. And even the costume alone doesnt work either, you cant hide your identity with an eye mask like this
Thats not true. While its not solely Robin's fault (the appearance of Robin coincided with DC's decision to brighten up and make Batman a kid friendly character), when Robin appeared Batman got an incredible makeover and changed radically. He was no longer a killer who was portrayed as a mysterious dark menace, but a blue, constantly smiling detective who worked during the day too. I have all the early Detective Comics and the early Batman issues
