Garth Ennis has never particularly liked conventional superheroes. He prefers to deal with antiheroes, which he considers more 'realistic'. That philosophy comes to a head with the Boys, a series where super'heroes' are kept in check by a ragtag team of CIA operatives.
The series set up is pretty simple. There's plenty of superheroes in the world, but they've stopped being particularly careful. Accidents get people killed to frequently, and that doesn't even get into what the heroes get up to when they think no one is watching. In comes Billy the Butcher. This guy has connections, skills, and a grudge against supers. What follows is your usual Garth Ennis collection of raunchy humor and ultraviolence, plus a few characters you can't help but like.
I like this series, but I hope it gets a bit more creative in the next couple of volumes.
