I mean the movie COULD be about him refusing to believe and accept he is Gothams true hero,like Harvey was.
Then by the end the truth COULD come out through whatever means,and Batman is cleared,and all his heroic acts throughout could pay off for him.
In the end feeling he has failed,as all the criminals Harvey put away are released and his reputation slandered. But Gordon reassures him Harvey wouldn't have it any other way,as he believed in Batman more than himself and now Gotham does. All the criminals Harvey put away,Gordon tells Batman they will both put them right back where they belong. So it ends on a bittersweet,but triumphant note.
Damn. You are nailing this! Great job Mr. Nolan..uh, I mean Rodrigo!
Seriously, I love it and its so logical that I have to believe that is what we'll see in the movie.
