WHO IS THIS FOR?
Batman and Harley Quinn isn't just tonally inconsistent from act to act, it's tonally inconsistent from second to second. Wildly inappropriate for children, too crass and silly for adults. Obscure lore and reference only DC-familiars will pick up on, but also completely out of character moments and scenes that will never fly with that same crowd. Both is and isn't set in the cult-classic Batman: The Animated Series Universe? Goes to the effort of getting DC voice alum Paget Brewster and the most famous Batman voice of all time, Kevin Conroy, but is stuck with Annoying-In-The-Wrong-Way Melissa Rauch to play Harley, who has never voiced the character before, and hopefully never will again.
But sadly, it's better than most animated superhero movies we're seeing these days.
Final rating:★★ - Had some things that appeal to me, but a poor finished product.
