"As a genre, the superhero movie is extremely versatile. Most superhero movies emphasize action and adventure, but they also commonly include elements of crime thrillers, science fiction, and fantasy. Horror, unfortunately, is a genre that is greatly underexplored in big-budget superhero movies. Early examples of superhero stories that toyed with incorporating horror include film serials; however, the superhero/horror formula remained rare on film. In the 1980s, graphic novels pushed comics towards an edgier tone. The trend of antiheroes flourished in the 1990s, and movies, especially low-budget movies, began to capitalize on the shift." - creepycatalog.com/
