While the movie flaunts much of the usual Batman "cool" throughout (including a new array of high tech gadgets and a motorcycle), The Dark Knight is a remarkably well written film that asks the audience just how far a hero can go before he crosses the line into darkness. Heath Ledger's Joker is easily one of the most terrifying villains ever to grace the cinema screen - described in the movie as a man with "no rules" and someone who "just wants to watch the world burn," he is a one-man show who changes overnight from an unknown thug into a universally feared "freak" who holds the city and its people in the palm of his hand. Dark, intelligent, and dramatic, this movie plays on the human psyche to create a masterful work movie-goers have to experience.
