YOU’D HAVE TO reach back into Marvel’s movie history to find a film quite as delightfully spry as Spider-Man: Homecoming—all the way back, in fact, to 2008’s Iron Man. That heartfelt romp not only fully rehabbed Robert Downey Jr.’s career, it also drafted a workable blueprint for the modern superhero flick, one that few entries have managed to follow. Nowadays, of course, Tony Stark is caught up in the globe-hopping skirmishes of the Avengers' saga, but in that first installment, he was just a semi-relatable, power-burdened weirdo trying to win over a girl and put away the bad guy; he came, he saw, he quipped fast. Later Marvel movies may have been weightier, but Iron Man’s light touch made it one of the best comic-book adaptations of its era.
