Maniac Hero (2016)

Frustrated by the urban decay around him, a convenience store clerk meets a young man equipped with Spider-Manlike gadgets, and - along with a high school nerd and a man with two mallets in his sleeves - they decide to become vigilantes. With notoriety comes attention, though, and a sharp-eyed businessman uses their example to create a sect of executioners. Nerdy superheroes in a film whose mash-up of styles, from action to drama, redefines offbeat comedy.
