I realize this makes me stupid, but I stopped comprehending parts of the plot about halfway through. Once the joker got arrested, I assumed the story was wrapping up and kind of zoned out. By then I was exhausted by the noise, fistfights, explosions and growly dialogue.
I also got majorly distracted by two teenagers to the front-right of me who kept checking their fucking text messages and distracting me with the light from their phones. I finally stormed over and did something that'd make my dad proud: told them to turn the fucking things off, and they did, looking a little scared. I'm easily half their size and twice their age, FWIW.
