You mean to tell me a guy who can take something as goofy as the earlier films and turn it dark, can not take a so called "goofy" character and make him as strong as any other character in his new films. He has created a whole different world and he can fix it that Robin or even NightWing can show up. If he really wants to make it up to the Robin fans he should and least be a part of a spin off movie. He doesn't even have to be the director. He could be a producer. There are great Robin and NightWing stories out there. Even the Let's Do This Crew like the Robin trailer on youtube.
If the director hates Robin so much why doesn't he just stop making the movies after this one. To me that would be better because:
1 If he really hates him that much I wouldn't want him to be the director to use the character anyway. He wouldn't do him justice.
2. Batman and no Robin is like Spencer for Hire without Hawk or Lethal Weapon without Danny Glover. You can do good shows and movies without them but sooner or later people will start to notice something missing.
