Despite its R rating, Flashdance is largely a fairy tale. Through the glitz and glamour and a vision of Pittsburgh that's somehow both a smoke-filled steeltown and the Emerald City of Oz, we can see a sly updating of the Cinderella tale, albeit with sex, Spandex, and lots of '80s pop-rock. Note that MTV was only a few years old when this movie came out; this was one of the first movies to successfully (and profitably) combine the visual razzmatazz of music-videos with a plot. The movie's slender, go-for-it premise proves a sturdy construction for all the music/dance scenes and inventively edited montages of blast-furnace steam, sizzling nightlife, and willowy Pittsburgh welder/dancing girl/ballet diva reverie.
Mawby's seems akin to all those escapist Golden Age of Hollywood musicals of the 1930s/'40s/'50s, where Broadway chorus girls did impossible "stage" routines on ice, underwater, on airplanes, places only an energetic movie camera could go. Alex and a few other dancers, briefly clad, do elaborate, self-choreographed avant-garde routines that mostly just bring polite applause from the working stiffs at the bar. If parents are bothered by the benign treatment of an erotic girlie club as a nurturing environment, there's a contrast provided later in the film between the risque but non-risky Mawby's, and Zanzibar, a strip joint where the less-empowered and less-fortunate girls seem to end up, explicitly nude and degraded.
