I give this points for trying something different, and I did enjoy the journey, but it didn't completely work. A person in the cinemas behind me sighed anytime a song was starting. She should've been sighing at herself for going in blind. The fact that it was a musical isn't the reason it didn't work though, but the songs do take up the running time limiting the amount the story can be moved forward. By the time it was reaching the end, I knew there wasn't ample time for the third act that I was hoping for. We don't actually see the famed partnership of Harley and Joker in this either that may cause some fans of the usual canon to be disgruntled. I was hoping when Joker escaped that it set up the sequel for that in some way. I had same feeling others have had about the ending. Was it in some way a response to the lunatic left for their deranged response to the first film? A kind of 'I told you so'.
