Sergio Bergonzelli made a name for himself in the '70s for outrageously sleazy sex films of the "bad = good" category. This escapist romp many years later is dullsville, and apparently was his final movie.
Seems SB had the starch knocked out of him somewhere along the line, judging from the timid results here. It does not resemble at all Salvatore Samperi's classic Laura Antonelli film MALIZIA, nor the goof-ball swingers SB made like IN THE FOLDS OF THE FLESH or EROS HOTEL. Instead we have generic soft porn reminiscent of those frothy German sex comedies with Olivia Pascal and a disco score.
There is an inordinately long disco scene in the middle of MALIZIA OGGI, centering around the film's thematic link to dance. Heroine Luna is a dance student who plays a practical joke on her Germanic dance teacher, having her kidnapped by a cretinous handyman who works at the disco (directed in very poor taste, and quite unfunny), so that her boyfriend's dad can replace her as teacher/choreographer.
Film's incest theme is not explicit but strictly roundabout, as the four main protagonists: Luna and her knockout step-mom (Valentine Demy, a beauty from Tinto Brass's stable) and hero and his dad mix & match bed partners. Add to the menage Luna's rich & goofy dad, who keeps cheating on Demy with their black (but blonde-haired) housemaid and you have cornball swinging sex action.
Pleasant enough photography of touristy Italian locations makes it easy enough to watch, but Bergonzelli's melodramatic edge is sorely missed. Even a scene where Luna is nearly raped by a pair of hooligans, turns into a cheap action sequence involving a budget-busting helicopter.
Basically it's only watchable to gaze at the too-good-to-be-real Demy and the full-figured Debora Cali as Luna. They re-teamed in Tinto Brass's classic study of prostitution PAPRIKA, but not in major roles.
