I would compare this show to the animated The Tick series, which is (per my handle) one of the highest compliments I can give. It’s goofy, over-the-top, frequently surprising, superhero silliness. The Thor movies wish they could be this much fun.
(Disclaimer, this show is very R-rated, and the punchline to a lot of the jokes is, “… and then someone dies in an extremely gory way.” So know that going in. Oh, and if you don’t like it at first, give it a full episode or so. I absolutely hated the first five minutes of the first episode, until I started vibing with what this show has to offer.)
But this show legit has good character development as well: Harley here is probably the best onscreen Harley there is. The Harley/Birds of Prey movie struggled and failed to deal with the inherent problems with Harley being a main character (namely that she is literally defined by the Joker) but this series tackles that head-on, and does a great job.
