The first three seasons of Harley Quinn were spectacular. The witty comentary on issues of Harley Quinn's evolution form Joker's Girlfriend to her own Villan was complimented by a ensemble of interesting characters that didn't hold any bars back in dialogue and expression of their own thoughts and actions. The show did a brilliant thing by mixing modern everyday life with the chaotic nature of supervillains and sometimes insane grotesque violence acts they do. However in season 4 they've tired to introduce the hero/villan dichotomy into the show by introducing the bay family and the old Harley Quinn Anti-Hero journey. I'm sorry guys but it just doesn't work when you have bat girl team up and be friends with Harley Quinn after she brutally murders people with a bat. When you introduce hard hitting moral heroes like Batman, batgirl etc, it's hard to bounce right back to aworkplace comedy/violent Villainous Escapades because it completely derails the hero's good intention in any validity. The last two qualms I have about the season 4 is how they make Bruce a horribly desperate loser, especially when it comes to Selina. Batman whole relationship with Catwoman is that he's in love with her but can't pursue that relationship because of his stance against all crime. His jumping over hoops for her makes no sense when his first commintment is always to be Batman before Bruce Wayne. Don't even get me started on Dick Grayson... they completely sucked away away his inner battle of fighting against the impulse to be his own hero that can balance his vigilante/civilian life versus being consumed by Batman's mission/crusade.
