There’s never been a more frustrating time to be a socially progressive fan of Marvel Comics. Not because its many titles are conservative or hateful — just the opposite, in fact. Marvel’s printed superhero books are more ethnically diverse, feminist, and queer-positive than they’ve ever been. The frustration comes because, even as Marvel’s printed offerings are looking forward, its popular live-action movies and TV shows feel like relics from a lily-white, male-dominated, straights-only past. It’s time for Marvel to push its onscreen output into the 21st century by learning from its own source material.
