Punk rockBut here's the big question: can Superman, the most squeaky-clean superhero ever written, actually pull off being punk? Superman meets punk rock: Yes, this actually happensSuperman doesn't waste time with another origin story. So yes, Gunn's Superman flirts with punk ideas, but corporate Hollywood keeps him on a tight leash. In other words: Gunn's Superman might not convince you he's punk rock in the same way Donner once convinced us a man could fly. James Gunn's Superman may not be the cure to superhero fatigue, but it's a shot of adrenaline in a tired genre.
