I'm going to avoid spoilers, but I really wanted this to be good.
Like Michael Keaton, I liked the idea of a Patterson Batman, because you'd never meet him as Bruce Wayne and think "Hey, that's Batman", but they honestly didn't even give him a chance to shine as either Bruce or Batty.
Like mystery boxes, a detective story only works if the pay off is worth it, it isn't. If they wanted a dark noir, they should have eaten the R rating and basically made it Rorschach with gadgets.
There is much more I'd like to say, but I'm not posting spoilers on a movie this new.
I'm a fan of comics, super hero movies, film noir, detective novels, and even cheesy movies, I'm the exact person this movie was made for, I was not entertained.
