Never Back Down (film series)

The Never Back Down film series consists of American martial arts sport movies, centered around an original story and characters created by Chris Hauty. The plot of each installment details the events that surround its various underdog characters, who must exceed expectations and overpower their more experienced competition in a variety of legal, semi-legal, and illegal MMA competitions.

The series as a whole has been met with mixed critical and financial successes. The original movie received poor response from critics, despite earning a profit at the box office. The second and third installments which followed earned praise from critics who considered them an improvement, though their monetary performance on home video is unknown. Conversely, the fourth film had mixed reception critically, with various reactions calling it inferior to its predecessors, while others believed it was a worthy sequel from the female perspective. Despite each movie's initial performance, they were later classified by some critics through modern analyses as some of the best classics of their genre.
