Most modern major films are shit for the same reason - they are aimed at teenage boys and become generic as few people are rilling to gamble on something new. Super hero ones are in fashion, so you get loads.
There are intelligent super hero comics, but they don't tend to get turned into films in favour of the generic fluff that has been proven to work. Unlikely they'd make Red Son, for example. Or even a fun Bizarro one.
Comics are better, anyway.
