Umberto Lenzi Giallo's range in quality from sublime to trash, but his earlier genre entries tended to be the best; and So Sweet...So Perverse is certainly at the higher end of Lenzi's Giallo achievements. One of the trademarks of Giallo is a high dosage of sex scenes; but despite the fact that this film has the word 'perverse' in it's title; So Sweet...So Perverse is actually not all that perverse at all, especially not by Giallo standards. Rather, the film focuses more on the plot details than perversity, and it just about serves it well. Italian directors were famous for ripping of successful films from other countries, and the plot here is clearly lifted from the French classic 'Les Diaboliques'. We focus on a couple with marital problems; Jean and Danielle. When Jean hears a woman screaming in the upstairs apartment one day, he immediately decides to investigate. There he finds Nicole; a woman frightened of her boyfriend Klaus. The pair soon begin to fall in love, but it later transpires that this was just a trap set to snare Jean...
So Sweet...So Perverse is a classy little thriller and much unlike later Lenzi Giallo's such as Eyeball, almost everything about the film is well done. The film benefits from a good cast, which feature early Lenzi muse Carroll Baker in the central female. Baker's role here initially appears to be a lot like her role in the earlier 'Orgasmo', but she soon gets to switch to a more interesting character. Baker is joined by the sexy Erika Blanc, and like most Giallo's with two sexy leading women; the pair do get to get it on, although you shouldn't go in expecting a full blown lesbian sex scene. Jean-Louis Trintignant rounds off the cast, but isn't given as much to do as the ladies. The plot does get a bit slow at times, but the film never slows down to the point of becoming boring. The second half is much more exciting than the first as that is when the plot gets into full flow. When the twists start to come into play, So Sweet...So Perverse really is an intriguing thriller and unlike many Giallo's, this one also features an ending that wraps most of the plot up nicely. This film is highly recommended to Giallo fans!
