Episode 3 is not the strongest we have seen from Harley Quinn season 5, but the DC series continues to be entertaining every week, which is perfect for such a long-running show. The first few season 5 episodes did a great job of setting the stage for where the season could go. While Brainiac and Metropolis are the biggest elements of the season, Harley Quinn still takes the time to keep the same hilarious hijinks fans have been used to seeing in the show.
