First of all, the director's vision, Nolan makes use of all his talent in the way he tells a story; brings us an adrenaline-fuelled thriller, wasteless dialogue and above all incredible character building.

The most reslating thing is the main villain, impressive Heath Ledger's performance that earned him the Superstum Oscar for Best Supporting Actor for that sadistic and cunning Joker. He is the soul of the film and who plays a fundamental role in the arc of the other characters. Especially from Bruce Wayne and Harvey Dent, who must ally themselves to stop it.

The script plays with the viewer on more than one occasion and tries to lead us to the chaos the Joker is looking for. It is essential to know that it represents the doom of humanity, selfishness and the destruction of society; while its counterpart (Dent) represents faith in humanity, sacrifice and honor. At first glance, good and evil are flatly identified, but it's just a strategy masterfully used as a metaphor to surprise the audience with an incredible script twist that will show that Harvey Dent (Aaron Eckhart) has the best arc in the trilogy (after Batman). And then give us a final masterful scene depicted in Batman's sacrifice to keep people's faith intact at the expense of their own reputation.

The music composed by Hans Zimmer for this film is masterful. And there is not a single technical detail that has not been carefully cared for by Nolan, he does not seek to exaggerate in visual effects; here he tries to be as plausible as possible, not forgetting that he is adapting a comic book.
