I guess my main problem with the Nolan series is that it totally removed the pulp aspects of Batman, which is the best part, in my opinion. I wouldn't mind a realistic Batman, but then, don't have Batman be the only guy with a fantastic costume. Just put him in a generic ninja suit with a Bat-like theme and lots of illusion, as was done so well in Batman Begins. Instead, it seemed to me that the series got progressively less magical, while the Batman character got progressively more superheroish, and the result in TDKR was, in my opinion, a little bizarre, especially when you ultimately get this guy in a bat suit fighting in broad daylight against a very generic backdrop. Contrast this with the excellent Scarecrow fear gas at the end of BB.
Ultimately, I thought and still think that the Di Caprio Riddler idea would have been a better conclusion to the series. There was a situation where you could have combined the Ra's Al-Ghul loose ends with another "weird science" genius, which is a great combo. Cat Woman, as she was written, served almost no purpose whatsoever, except to give Bruce an exit. I would have liked to see Bruce's destiny to be a bit more than moving to Italy. I wanted to see a real Lazarus Pit, and clever international detective work as Bruce, etc.
