Harley Quinn is apparently dumped by the Joker and she’s fair game to all those who hold a grudge against her. That’s the premise of this good entry in the DC universe. Margot Robbie carries a lot of this film as Harley Quinn. Good supporting cast as well with Rosie Perez and Mary Elizabeth Winstead. It’s a movie that works because it keeps the story simple and definitely does not take itself too seriously.
