I avoid most of them myself. I grew up reading superhero comics mixed with children's and adult novels, but I find the superhero movies pretty uninteresting on the whole, bland combinations of endlessly iterated origin stories and reboots with big monotonous fight scenes and obvious CGI.
I prefer the new wave of superhero TV series, since they capture to a greater extent the convoluted and extended stories found in the comics.
As proof that superhero material CAN comment meaninfully on social realities - which was Guillermo del Toro's call to young fantasy and genre directors at the Oscars - I offer Kurt Busiek's and Alex Ross's Marvels (1994). It would make a great movie if done right, but is downbeat and would be very expensive, so it will never happen.
