First of all, I would ask those who are not familiar with the syntax of Horror cinema to refrain from making stupid comments. In America, Argento is studied in film schools, and Profondo rosso is the Thriller that forever changed the genre (along with The Exorcist and The Texas Chain Saw Massacre). To describe Profondo rosso, from the camera movements to the cinematography to the soundtrack, would require a whole book. The mere scene of the dialogue between Hemmings and Lavia at "Piazza del Nettuno" in Turin, with the famous "Pop Art" painting recreated, is worth the entire filmography of many directors or self-proclaimed ones... On the other hand, Argento was the godson of Sergio Leone, and this is evident until 1987. The film's aesthetics, the "non" essentiality of the plot, even though twists were not lacking until "Tenebre," and the narrative construction was still interesting...
Giallo has some magnificent sequences, I would dare say lush, in a cinema (the horror one) now reduced to being television transported to the big screen in the vast majority of cases... I’ll just mention the dolly shot in the inevitable theater and the one in the fashion Atelier... In the sense of, we know how to move a camera... Then everything gets lost along the way, and Giallo is far from being an interesting film.
Those who criticize "4 mosche di velluto grigio" probably do not know that only the final scene was shot with a German camera that at the time belonged to the scientific structure that would later become CERN... One of the greatest slow-motion scenes in cinema history, alongside that of "Little Big Man" by Peckinpah... What does Bud Spencer have to do with this? What kind of phrase is that? What does Robert De Niro have to do with the latest film by "Muccino"... Come on, please... Moreover, 4 mosche di velluto grigio is, if we want, the "embryonic" version of Profondo rosso, and already in this film (and not in the previous ones), the aesthetics and themes of Argento to come begin to take shape...
Let’s not even talk about Suspiria, which is constantly cited by Wes Craven, John Carpenter, Tobe Hooper, and all the others among the most "revolutionary" and "subversive" Horror films... Just the sets, the cinematography of this film deserved a couple of Oscars... Argento is old, gentlemen, but above all, he has always lived "dangerously"... He is a true, authentic anarchist, and perhaps represents in Cinema what De André has represented in music. He has many analogies with Faber... A wealthy bourgeois family, youthful rebellion, and unpopular choices. He breathed an intellectual and cultured family background and tried to "refresh" a genre that until then in Italy was a carbon copy of the Anglo-American one... To the good grace of Freda and Bava.
His "losing his way" coincided with a "messed up" private life, full of unresolved issues, drugs, and alienation... Argento is a misanthrope, shy, a voracious consumer of cinema and music... He listened to Tangerine Dream or Pink Floyd, progressive rock and Fusion when in Italy, the vast majority of people didn't even know who they were...
Robert De Niro hasn’t made a noteworthy film in at least 20 years. Does this make him a bad actor tout court? Carlo Verdone stopped doing "commedia all'italiana" at least 15 years ago (to be generous)... Should we throw him out altogether?
Chaplin, in the second half of his career, made some sound (stricto sensu) nonsense: should we consider Chaplin a hack then?
I would ask for reflection before hitting the keys... Always...
