It would have been better as a stand alone vs homage to the Joker.
It also should have added a bit more rise and fall. More epical irregardless of its effects on society. Thats not to say I didn't like it. Its just that my expectations were a little too unreasonably high because I loved the trailer and the idea of what they envisioned for this film. I will see it again because I was tired in the theater watching it the first time. I still feel like some elements were missing from this movie.
