I think it's pretty obvious what he's doing. Trying to make it sound like none of the blame should be placed on him. He didn't disappoint "some" people. The guy made a piece of trash film and he knows it. It earned less money than it cost to make. That's more than just "disappointing some people". What they (not just he, but everyone involved) did was alienate Batman fans worldwide. And the way he's acting like we have no right to be upset about it ticks me off more than just a little bit.
"There is an idea of a Patrick Bateman; some kind of abstraction. But there is no real me; only an entity, something illusory. And though I can hide my cold gaze, and you can shake my hand and feel flesh gripping yours and maybe you can even sense our lifestyles are probably comparable... I simply... am not... there."
