Long and busy mature comic action movie

Rating: 7/10 (10 April 2016)

A bunch of guys with clown masks rob a bank, but as steps of the robbery are completed, one clown kills another that isn't necessary anymore, until there's only one left at the end who leaves with all the money. It's the Joker. The money he stole belongs to the various town mafias.
Some gangsters are intercepted by a bunch of guys in batman suits until the real Batman shows up to kick butt, and gets himself bitten by Rottweilers.
The Joker crashes a gathering by all the towns mobsters and offers to take out Batman for half of all their money. They aren't happy. One of them puts a price on the Joker's head. And when his body is delivered he just stands up and takes out the mobster.
Batman decides to grab the Asian accountant to the mob from Hong Kong. The DA in the meantime indicts the mobsters, all 500 of them and becomes a star. He's dating a girl who used to date Bruce Wayne. The Joker warns the town that he will continue killing people unless Batman reveals who he really is. And to make his point kills a judge and some other city official presiding over the mob trials. Now the commissioner and mayor are in his sights. But eventually the Joker gets himself arrested. But that was his plan. Now he has access to the accountant.
Once he escapes he grabs the DA and the girl and gives Batman the choice to rescue one of them as he has both in different buildings ready to blow up. The girl doesn't make it and the DA ends up with half his face burnt. He now engages in a violent revenge spree.
The Dark Knight is a comic hero for adults. It's about a city facing an asymmetric battle with a criminal who believes in no rules and as a result brings about chaos. This isn't your linear story where our heroes are destined to do this action, but here choices have to be made. Bruce Wayne has to decide whether to show his true identity, whether to save the girl or the DA, and so on. The DA uses flips of a coin to decide whether he'll kill someone or not. As a result of the chaos the Joke brought, logical thought isn't the answer, but blind chance is, he thinks.
As a result of the maturity, there are less cool gadgets. Batman's lair is strikingly sober and empty. So is Batman, who isn't quite the charismatic socialite we expect. In fact, one get the impression that Wayne and Batman don't even show up all that much in this movie. Part of that is that the story requires a lot of screen time for the commissioner and the various villains, of whom the Joker steals the show, albeit being a dislikable villain. This is not some cool and admirable villain who gets to give cool speeches. This guy is ugly inside and out, whose false speeches are indeed a challenge to reason. They created quite a unique and daring character.
As most Nolan movies, this one, too, could have been trimmed by 30 minutes to make tighter movie. Perhaps give us less of the DA and more of Batman. There's just too much going on here and not all works.
