This film really brought to mind an earlier time, when communal bathing was common—I recall sharing with my sister for thirty minutes and using carbolic soap! While the movie doesn’t quite have attendants as attractive as "Susan" (Jane Asher) or “Mike” (John Moulder-Brown), most of the story unfolds through the eyes of this young man who's constantly preoccupied with lusting after his coworker. He’s portrayed as naive, and consequently receives a lot of attention—and money—from the customers, particularly Diana Dors. "Susan" embraces life to its fullest extent, which doesn't sit well with “Mike,” who becomes increasingly jealous. He begins trailing her and discovers that her boyfriend, also named "Mike" (Christopher Sandford), is rather dull, and she’s involved in an affair with his teacher (Karl Michael Vogler). At some point, he acquires a life-size cardboard cutout of the woman he desires, as the latter portion of the film veers into what I felt was overly ridiculous, hormone-fueled comedy. The film received an X rating due to nudity, which appears sparingly near the end; mostly, the sexual content exists within the young man’s imagination. Moulder-Brown does a decent job conveying his character's sexual frustration—something I think many people can understand. Asher is also effective as someone who enjoys playing with him, and their initial game of flirtation (with her firmly in control) was entertaining for about an hour. After that point, however, I began to lose interest and felt the film slowed down considerably. It’s probably worth seeing, but it has sadly lost much of its impact.
