I hated the 3rd Batman movie, but don't get me wrong, it was an enjoyable movie, it just got everything wrong.
Bane: Why does he sound like an evil Santa Claus, when his is mexican?
Bat-man: So much grunting and yelling, from a hero who works in the shadows, he had ninja skills in the other last two move, but he acted like an old man in this one.
Cat Woman: Ann Hadaway is no Michelle Pfeiffer , but she tried.
Ra's al Ghul: For one short scene in the movie, its like they didn't even try to bring him back from the dead, which is what Ra's al Ghul does, with the lazarus pits.
Talia al Ghul: Cheesy story with her mad at batman for killing her father, who is known to never die, and then kill her off as well......and with that, they ended batman.
Robin : At the end of the movie, really? 
I just don't see a part 4th happening.
