Going through mid life crisis myself, I can relate this movie in many levels. Firstly, this movie is a classic representation of human mind. How dangerous, manipulative it can be, Secondly there is no true love , Lastly joker is not a person its a thought that any one can carry its legacy.
But.. But Todd Phillips , philosophy could have been better if the movie or character name could have been something else other than "Joker". Because DC fans will never accept this as the "JOKER" movie especially when after late Heath Ledger left the character as a behaviour in everybody’s mind.
Could have done better Toddy
