I thought she was lesbian for the first half of the movie until her 'girlfriend' dropped off the face of the Earth (or at least Gotham) in the second half. Then Hathaway had the biggest character change in record time, which was about ten minutes. I didn't like that she didn't get enough screen time, nor did they actually call her catwoman - that would feel out of place but it's not very important - because she was an interesting character, who had decent chemistry with Christian Bale.
I probably missed something, but (major spoilers here):
Spoiler:So why the hell did Bane work for Daggett? I get that Daggett used Bane for the stock market crash and to make Bruce Wayne broke, which would eliminate his competition. That's fine. Then we discover that Bane worked for Daggett to access Wayne's Applied Sciences Laboratories. He broke in by blowing up the floor from under it, because he built directly under the facility, so why the hell did he even work for Daggett? Forgive me if I completely missed something, because I cannot understand what he was saying half the time, so it was a bit distracting.
Oh, and Bane's death was so anti-climatic. He got shot and boom, he's dead. Kinda mellow for a guy that is the title villain for the movie. They just left him to die.
Not sure if someone already mentioned this, but this movie felt more like the typical super-hero movie in the way it was told, more so than its predecessors anyway. In any case, I thought the ending wrapped everything up, no matter how cheesy it was.
The Robin thing was cool. I would love to see something like Batman Beyond.
Spoiler:
I thought its cause he was really working with Talia. And he wanted to force Bruce to give Talia the energy device and embed his trust in her so he used Daggett as a catalyst for that. Remember he said something like "Why am I not the owner of Wayne Enterprises" or something to that extent. And Bane says something like "You never were intended to be". So it seems like they planned tricking Bruce into trusting the Miranda front from the beginning.
