This is what usually happens in the months leading up to any Nolan Bat-film. Prior to the release of Batman Begins, people were complaining about Batman's costume, that The Scarecrow only wore a burlap sack, that Ra's al Ghul was apparently Asian, the Batmobile looked too much like a tank and not like a traditional muscle car, etc etc etc.
The same thing happened in the months leading up to The Dark Knight. People complained that Heath Ledger was all wrong for The Joker, that The Joker wasn't "perma-white", Maggie Gyllenhaal wasn't attractive enough for Rachel Dawes, Batman's costume was too segmented and robotic looking, and the list continues.
People are going to complain before The Dark Knight Rises opens. It's just natural, and the way of the universe. Of course, when people started seeing actual footage of the movies, they changed their tune. I remember in 2007 when people were so against Ledger as The Joker, and then the theatrical trailer debuted in December and people were over the moon.
I look forward to the release of the theatrical trailer, which will probably sway a lot of people who are either indifferent or disinterested in the film thus far. I've witnessed it two movies in a row, so I'm pretty sure the same will once more transpire for this one. In the end, despite all of Nolan's unfavorable decisions in regards to the comic-book accurateness of costumes or certain details, his films have always been excellent, and that's what I'm most looking forward to: a good movie.
