Since the inception of cinema, genres have begun to take shape and transform, beginning with the basics like drama, romance, and comedy. With an over-saturated film market, the industry is constantly evolving and inventing new niche genres. As a subgenre of crime films, police films have gained a great deal of popularity over the years, with the buddy cop genre proving popular with films like 21 Jump Street and Ride Along, which left audiences laughing at the jokes and thrilled by the action at the same time. That being said, not all cop films are comedies.
