Since 1979, CinemaScore has surveyed opening night audiences for wide releases from an A+ to F scale. In their polling, there’s a list of just 22 movies directed by some of the most revered filmmakers of our time: Steven Soderbergh, William Friedkin, Robert Altman, Jane Campion, and more. They’re the movies that received an F.

Once a market research statistic, the F CinemaScore has become something of a badge of honor. It spans the punk rock to the artistically inclined, the morbid artifacts to the subsequently acclaimed. What audiences saw as betrayals may have indeed been grand subversions playing in malls across America fueled not by irony, but by an unbridled earnestness rare in contemporary film.

Now, with Who Gives an ‘F’, it’s time to reappraise some of the most rejected films of the last half-century. Come and see them sans marketing pitfalls or multiplex expectations—and don’t forget to grade the movie on your Music Box Score card on your way out!
