I saw the movie this afternoon and while it's supposed to be a stand alone movie outside of the DC Extended Universe, I do like what they've done with Batman canon. I also know Batman canon has often been "retconned", regardless I won't give too much away but there are quite a few aspects of this film I liked. If you know Batman canon Joker really is an unstable character.
My favorite movie line if you will was something I tweeted once I left the movie.

Then I said no I won’t because I’ll be a comedian!
And now I’m a comedian and now no one is laughing!”
