The film received negative reviews.
Janet Maslin of
The New York Times wrote that the film "turns into a preposterously self-serving variation on 1960s' themes" and that the central problem in the plot "is certainly a real one, for rock radio stations everywhere. But Ezra Sacks's screenplay manages, by taking this crisis so very, very seriously, not to take it seriously at all."
Variety called the film "the modern equivalent of the 1930s newspaper film, all break-neck dialog, quirky happenstances and behind-the-scenes drama transposed to a 1970s rock radio station. Unlike such classics as the original '
Front Page,' however, this Universal release goes nowhere with a potentially-fascinating set of plot elements."
Charles Champlin of the
Los Angeles Times declared it "Fairly Mediocre" and "such claptrap silliness that only the tender in years and soft in mind are apt to be enraptured." Gary Arnold of
The Washington Post panned the film as "a shallow attempt at rabble-rousing comedy" which "flounders in smarmy virtue" and "tries to be hip in all the worst ways." John Pym of
The Monthly Film Bulletin wrote that the movie's central premise rests on the idea "that commercial, pop-music radio stations were not primarily created to generate advertising revenue, and that the people who put on the records and ad-lib between the jingles are folk heroes, free from the exigencies of the business world, members of that select cinematic breed of American independent professionals. Ezra Sacks' attenuated script, which alternates between episodes of jovial high jinks and moments of melancholy self-indulgence, fails to acknowledge the practical implications of this premise (namely that, without advertising, these 'creative' broadcasters would be out of work) and instead makes the army salesman a ludicrously over-drawn figure of fun and Regis Lamar a sycophantic yes-man."
Rolling Stone magazine considered the music heavily biased towards musicians who had been managed by Irving Azoff, who would become the head of the studio's then-corporate sibling
MCA Records five years after the film's release. The film holds a score of 20% on
Rotten Tomatoes based on 10 reviews and was not successful at the box office. Some reference books claim that the sitcom
WKRP in Cincinnati was based on
FM. The physical resemblance between Michael Brandon and
WKRP lead actor
Gary Sandy and the fact that their respective characters were both based upon
KMET programming director
Captain Mikey may have contributed to this speculation. However,
WKRP series creator
Hugh Wilson asserts that the sitcom was already in development when the film came out. He also states that he was "scared to death" when the film came out, afraid that it would eclipse the CBS sitcom, which made its debut in September 1978. Wilson was relieved when
FM came and went from theaters quickly. ==Soundtrack==
