Batman: The Dark Knight Returns
If any comic has a claim to have truly reinvigorated the genre, then The Dark Knight Returns by Frank Miller--known also for his excellent Sin City series and his superb rendering of the blind superhero Daredevil--is probably the top contender. Batman represented all that was wrong in comics and Miller set himself a tough task taking on the camp crusader and turning this laughable, innocuous children's cartoon character into a hero for our times. The great Alan Moore (V for Vendetta, Swamp Thing, the arguably peerless Watchmen) argued that only someone of Miller's stature could have done this. Batman is a character known well beyond the confines of the comic world (as are his retinue) and so reinventing him, while keeping his limiting core essentials intact, was a huge task.Miller went far beyond the call of duty. The Dark Knight is a success on every level. Firstly it does keep the core elements of the Batman myth intact, with Robin, Alfred the butler, Commissioner Gordon, and the old roster of villains, present yet brilliantly subverted. Secondly the artwork is fantastic--detailed, sometimes claustrophobic, psychotic. Lastly it's a great story: Gotham City is a hell on earth, street gangs roam but there are no heroes. Decay is ubiquitous. Where is a hero to save Gotham? It is 10 years since the last recorded sighting of the Batman. And things have got worse than ever. Bruce Wayne is close to being a broken man but something is keeping him sane: the need to see change and the belief that he can orchestrate some of that change. Batman is back. The Dark Knight has returned. Awesome.
