After watching both seasons I think certain parts was enjoyable but sadly it makes me classify the unexplained or otherwise nonsense in the show as a "Harley universe" to explain the tasteless plots, disappointing character development and forced perspective.
I find characters like Wonder Woman popular because she faces competent female/male villains that shows her overcome an adversary of great strength and intellect which shows how great she is overall. Harley faces so many heroes and villains in this series and they seem to be weak, ignorant character's which only outlines how insignificant she is. Poison Kitey were what held my family's interest in the show, but even that was a predictable dissatisfaction of what could have been genius in contrast to the way it ended.
