Taken as a psychological thriller, this is a marvellously well-made piece of work. Chabrol is a master of subtle storytelling, and even though you know exactly how the film will end right from the first few frames, he still manages to work up some suspense and creepiness. Taken as a "serious" social statement about class distinctions, it's a complete failure (the supposed "target" of the film, the bourgeois family, comes off as very likable). So take it as a thriller, and you'll be fine. (***)
