The movie was alright. There were a lot of issues, like many have said: the pacing was off, the tone was all over the damn place, and some of the characters felt shoehorned in. Also, I hated that thing where they'd introduce a new main character by pausing the screen and showing their name and stats. Took me right out of the movie, it just seemed like such a weird choice. And I didn't care for Jared Leto's Joker, either. He constantly sounded out of breath, he looked like he was designed by a 14-year-old Hot Topic employee, and he came across like someone who's never seen anyone who's legitimately crazy, trying to seem crazy.
Speaking of, I honestly worried that they would downplay how messed-up Harley and Joker's relationship was, moreso than they did, anyway, but you could at least see it. Still, I wish they'd taken it a bit further, because looking back at the Batman animated series Harley originated from? That shit's kind of shocking to watch now.
Viola Davis and Margot Robbie stole the fucking show, too, both of them were awesome.
