the portrayal of Catwoman and the climax of the movie.
I didn't really like Catwoman's costume in the movie, and I thought her main motive was odd since she wanted a program to erase her records but I have to believe there were paper copies and people who knew what she looked like so I didn't really see how it was going to fix her problems. I also thought some of her movements were ridiculous, the fact that every time she was in her costume and walking around she had to have a major butt waggle was odd.
As for the climax, the police against the criminals fight was beyond ridiculous, like the police go rushing in towards a well armed group like this is some kind of medieval fight, and they had no formation at all basically just a mob, and then towards the end a bunch of them were just standing around clumped together asking to be shot. I also wasn't sold on Bane's sudden lose of power, I don't think having the tubes into his mouth removed would suddenly make him so weak, it felt like it was just a plot device to shift the focus onto Talia al Ghul. After that though everything was much better, and I thought the conclusion was great.
