With Harry Callahan getting up in years, the inevitable `old man with a chip on his shoulder' story had to come into play eventually. Callahan, looking fragile sometimes and out of place, his demeanor still was unwavering. Thankfully, this film took some time off to develop a different type of story, one that might reinvent the Dirty Harry and the whole genre. While the film fell short in doing so, it was still an excellent addition to the series, even if it was getting a little out of place during a time of silly fashion trends and New Wave music.

Tainted look at kibbutz life
This film is less a cultural story about a boy's life in a kibbutz, but the deliberate demonization of kibbutz life in general. In the first two minutes of the movie, the milk man in charge of the cows rapes one of his calves. And it's all downhill from there in terms of the characters representing typical "kibbutznikim." Besides the two main characters, a clinically depressed woman and her young son, every one else in the kibbutz is a gross caricature of wellevil.
The story centers on how the kibbutz, like some sort of cult, slowly drags the mother and son deeper into despair and what inevitably follows. There is no happiness, no joy, no laughter in this kibbutz. Every character/situation represents a different horrific human vice like misogyny, hypocrisy, violence, cultism, repression etc. For example, while the protagonist is a strikingly handsome European looking 12 year old boy  his older brother is a typical kibbutz youth complete with his "jewish" physical appearance and brutish personality. He cares more about screwing foreign volunteers than the health of his dying mother. He treats these volunteers like trash. After his little brother pleads of him to visit his dying mother whom he hasn't seen in a long time due to his military service, he orders, Quote  "Linda, go take shower and I cum in two minutes."
There is one other "good" character in this movie  a European foreigner who plays the mother's boyfriend. When the animal rapist tries to hit the mother's son, the boyfriend defends him by breaking the rapist's arm. He is summarily kicked out of the kibbutz then for "violent" behavior against one of the kibbutz members. More hypocrisy: The indescribably annoying French woman who plays the school teacher preaches that sex cannot happen before age 18, or without love and gives an account of the actual act that's supposed to be humorous for the audience, but is really just stupid. She of course is screwing the head of the kibbutz in the fields who then in turn screws the little boy's mom when her mental health takes a turn for the worse.
The film portrays the kibbutz like some sort of cult. Children get yanked out of their beds in the middle of the night and taken to some ritual where they swear allegiance in the fields overseen by the kibbutz elders. The mother apparently can't "escape" the kibbutz, although in reality, anyone was/is always free to come and go as they choose. It's a mystery how the boy's father died, but you can rest assured, the kibbutz "drove him to it" and his surviving parents are another pair of heartless, wretched characters that weigh down on the mother and her son.
That's the gist of this movie. One dimensional characters, over dramatization, dry performances, and an insidious message that keeps trying to hammer itself into the audience's head  that kibbutz life was degrading, miserable and even deadly for those who didn't "fit in." I feel sorry for the guy who made this film  obviously he had a bad experience growing up in a kibbutz. But I feel as though he took a few kernels of truth regarding kibbutz life and turned them into huge atomic stereotyped bombs.
