The B-action subgenre features lower budgets, simpler plots, and lower production values compared to bigger budget mainstream action titles. Originally used in a derogatory manner, the subgenre has evolved to describe a specific type of filmmaking with its own unique charm and appeal. The "B" designation originally referred to the second feature in a double feature presentation, with the "A" film being the main attraction. Over time, "B-movies" became associated with low-budget and less prestigious productions.
