Taking the themes, situations and consequences of the unique world defined in Batman Begins and running with them, The Dark Knight turns them into an unstoppable juggernaut. From the elegantly choreographed opening to the chilling ending, the pace is relentless. There is a lot of plot crammed in, although it is never confusing; like all Nolan films it demands the audience try to keep up. Sometimes the main character seems to get lost beneath emotional exploration of the supporting cast, but if Batman Begins was a film about how Bruce Wayne defines himself, this is a film about how others define themselves around him. It focuses on his most central relationships; Eckhart's hauntingly tragic Harvey Dent, the development of Oldman's superlative James Gordon and Ledger's supremely unnerving version of the Joker, simultaneously unlike any seen before and yet a spot-on translation regarding his reaction to, and interaction with, the caped crusader. This in turn reflects back on to the one element of Batman not quite done justice in the first film; how far he will go to complete his mission. Indeed, like the first film character development takes centre stage, but this sequel introduces a slew of philosophical points about the nature of society, heroism and morality to mull over. Arguably this entry in the trilogy best represents our hero by focusing on his internal conflict between those two defining traits; his unwillingness to compromise and his compassion. Yet that's not to say there's some unforgettable action and edge-of-the-seat suspense; this is an experience that, like the Dark Knight himself, gives everything and more.
