Few genres benefit from the art form of film as much as the action genre does. More grounded, less explosive genres (like crime, mystery, or drama stories) sometimes work just as well in novel form or as stage plays, for example, as they would in the form of a movie. Yet while there might be some good action-heavy books out there, there's an argument to be made that action just hits harder when it's visual, audible, and presented on the big screen.
