IMHO, later Hitchcock, including "Frenzy" (1972) seems very cold-blooded. Always strongly disliked that film. No sympathy for any characters in that one.
"Two Women" (1960 - Vittorio De Sica) depicts the rape of a 13-year old girl and her mother in WWII Italy. Harrowing. Much more so than "Frenzy".
It was shown on Boston TV in the mid-'60s, back when broadcast codes were pretty strict, several years before Hitchcock made his film.
I love Frenzy. It's pure anger and misanthropy. Compare it to his next and last film (Family Plot) which is a good natured amoral wink.
