2. 'Batman: Year One'
In retrospect, it's an unlikely collaboration: the operatic grandeur and bombast of Frank Miller in a writer-only role, wedded to the stylishly minimal art of David Mazzucchelli, who'd soon retire from superheroes entirely and reinvent himself as an alternative-comics trailblazer. But their definitive account of both Batman and Jim Gordon's earliest days as crime-fighters is the perfect blend of pulp and poetry; Nolan all but used it as proof of concept for his franchise reboot, and many fans and critics consider it the best superhero comic of the modern age. (Note to Marvel movie fans: Miller and Mazzucchelli's Daredevil: Born Again is arguably modern Marvel's best book, too.)
