"Overall, The Dark Knight is a very entertaining film, with little-to-no concerns about language. There is a lot of violence, but almost nothing graphic or particularly gory. Much of the violence is left up to the imagination of the viewer, rather than clearly depicted on the big screen. There are a few instances in which alcohol is shown and consumed, and in one place it is applauded as a means of coping with challenges or threats. There is very little sexual content to speak of, although girls in bikinis are shown, and at one point Bruce Wayne walks in on a couple clearly either about to begin, or just finishing an apparently casual sexual encounter."
