This is truly a disappointing experience : I had often to fast forward since I am a great fan of the Fruttero & Lucentini's novel and of the movie made lavishly in 1970s Turin by an excellent Comencini starring unforgettably classy Marcello Mastroianni, Jean Louis Trintignant, Jacqueline Bisset (at her prime) and delightful Aldo Reggiani as Lello Riviera. Here everything feels all muddled up into something that rarely is watchable, certainly does not have class, nor a strong grip at direction, but exceptionally just manages to land terribly flat on a small screen (small budget feeling) production that is as full of boredom and plot holes as it is full of trite situations, poor character's development. And, excuse me, aside Roberto Zibetti who I must say did well in the Trintignant's role, the cast seems to awfully struggle to give truth and realism to an upper class period context that should have been impeccably told and reconstructed but that lacks style from virtually any angle. I tried to forget- from time to time- the excellent novel and old movie, but in vane! The 1975 perfectly witty, cruel, ironic, and ambiguous movie still feels brand new when you are watching this poorly adapted, loosely written, badly acted, and presented version I highly not recommend seeing to anyone: it is just something you do not wanna be investing any of your time with, something that spoils rather cheaply what was a perfect gem of the Giallo's genre especially so celebrated by its fans who here in the U.S. would be truly 'screaming for murder', but not in the good old way.. If you know what I mean!
