"Most regular superhero books are designed to go on forever; of course, very few of them do, but the point is they are trying to throw mud against the wall and hope it will stick, and most of it slides off"

In this quote, Garth Ennis is discussing the nature of superhero books and their longevity. He suggests that most superhero books are created with the intention of being continuous series, but in truth, just a few of them in fact last for a significant amount of time. Ennis compares this to tossing mud versus a wall and hoping it will stick, indicating that the creators of these books are taking a chance and expecting success, however ultimately, the majority of their efforts will not be successful. This quote highlights the unpredictable and competitive nature of the comics industry, where even the most popular superheroes might not have an enduring effect.
