I thought is was amazing and can totally understand why it has done so well at the box office (first R rated film to get over 1 Billion dollars at the box office!)
I think the critics are wrong though. This movie isn’t about someone heading into decline, i’s a bout someone at the bottom being re-born. This is the birth of a supervillain – people as dastardly as Joker have absolutely no believe that they are evil, they may think they are a little tougher than some of the namby pamby pinko liberal doo-goody-goodies, but evil, naaa – righteous!
Joker set himself up as a leader of plebs and villains in teh only way possible, a rebirth.
Absolutely wonderful film!
