Chabrol is an acquired taste, so the two Arrow box sets are not only great value (especially at Amazon discount prices) but also a good way to get a taste for the cool detached droll pleasures of Chabrol's cinema.
Individually the films can seem slight but collectively Chabrol's approach becomes clearer & more enjoyable. Basically, he uses popular mainstream genres (eg the Hitchcockian psychological thriller) but uses them as a vehicle for his obsessions involving questions of guilt & justice, as well as for satire at the expense of the French bourgeoisie & authority. But it's probably a mistake to take the films too seriously, mostly Chabrol (like Hitchcock) seems to enjoy playing around with the stock plots, scenarios and characterizations of thrillers as a pleasure in itself.
Chabrol's good films work both as thrillers and as darkly comic "deconstructions" of the genre, but the less good films become little more than uneven potboilers. Almost all the films in box set volume one are good - deliciously plush & perverse efforts from Chabrol's late 60s / early 70s heyday. I have to say that this second volume (six films), on the other hand, is a rather motley collection.
"Road to Corinth" is cheapo 60s B movie spy thriller, though enlivened by the presence of Jean Seberg. "The Breach" is nutty over the top melodramatic farce. "Pleasure Party", about a man's pathological jealousy finally becomes untenable & genuinely nasty. Not a pleasant film. The seductive "Innocents with Dirty Hands", with Romy Schnieder as the murderess on St Tropez, is close to being classic Chabrol despite an overly convoluted plot.
The box ends with two films from Chabrol's late return to form. "Cop au Vin" is a decent 1980s murder mystery which allows Chabrol lots of opportunity for indulging in his Hitchcockian wickedness. "The Flower of Evil" (2003) is probably the most successful film here, revisiting archetypal Chabrol territory - the violent & perverse secrets that lie behind the facade of an upper middle class family and the question of what actually constitutes guilt. Excellent performances from the starry cast.
Anybody interested should definitely get Collection volume one first & then, if you acquire a taste for Chabrol, get this second volume - by which point you'll probably be addicted and more than happy just to sit back and enjoy watching them all without judging each individual film too harshly.
