Rating: 9/10 (30 October 2016)

The Dark Knight is a movie that is primarily about the battle of Batman versus the Joker. In this movie, Batman, or Bruce Wayne, is played by Christian Bale, and the Joker is played by Heath Ledger. The new district attorney for Gotham, Harvey Dent, who is played by Aaron Eckhart, is fighting crime in the court room, putting much of the mob in prison. He aids the Batman, as well as Lieutenant Jim Gordon (Gary Oldman) in trying to take down the Joker. The Joker tries to get under their skin, forcing them to do things they would not typically do.
One theme for The Dark Knight is the fight of good versus evil. Throughout the entire movie, the Batman is trying to stop the Joker from committing all of his crimes. The Joker even manages to turn the people of Gotham against the Batman, making it seem as if he is partly responsible for all of the bad that is happening. Harvey Dent was doing everything that he could to legally take down the Joker, and Bruce Wayne saw this as being very important. However, after the Joker killed Harvey's fiancée, Rachel (Maggie Gyllenhaal), Harvey turns bad, and starts to kill people himself. After the Joker was captured, this caused another evil for Bruce Wayne and Jim Gordon to fight. Harvey does end up dying, and Bruce Wayne has Jim Gordon lie and say the Batman was responsible for the people that Harvey killed, in order to preserve the image of Harvey Dent and all that he done for the legal system in Gotham.
Another film that is similar to The Dark Knight in theme is Spiderman. This film also uses a masked vigilante to fight crime in the city. A similarity is even though both Batman and Spiderman are trying to take down crime for the better of the city, they get made out to be the bad guy when things are not going so well.
One way that good versus evil is demonstrated in the film is when Harvey Dent gets his face burned after an explosion. The idea is introduced earlier in the film, when Harvey refers to people calling him "Harvey two face." The good versus evil is symbolized by Harvey's two sides of his face; the burnt side, and the non-burnt side. This is when Harvey took a turn towards a villain. He even has a quote within the film, where he says "You either die a hero, or you can live long enough to see yourself become a villain." Another symbol of the good versus evil theme is Harvey's coin. Throughout the film, Harvey used his coin, which has heads on both sides, to "make his own luck" as he states in the film. After the accident when he gets burnt, however, one side of the coin gets burnt as well. From then on, he used the coin in deciding whether people would get to live or die. The two sides of the coin symbolize the good versus evil theme.
