You think of comic books, and you immediately flash to capes, tights and female heroes wearing leather jackets over tight spandex thanks to an awkward design phase from the 1990s. But comics are so, so much more than that. You’ve got a side of the medium that is all colourful and high in action. Then you’ve got another side, a darker reflection for more mature audiences where actions have consequences and there isn’t always a happy ending. And that’s the side where you’ll find John Constantine, the Hellblazer.
