The Gist:
Cache (or Caché) is a film with a Hitchcockian style of suspense, only with this film the threat is extremely abstract. It is simply videotapes of someone watching their house, then a videotape of the husband's home as a child, then a videotape of the husband's vague conversation with another man, and so on. These tapes fill the opening moments with a feeling of dread, but that slips away as the film goes on. In its stead is the mystery of who is sending the tapes, the mystery of the husband's past, the mystery of the wife's potential affair, and so on. In fact, the film has a tendency to take something severe and then soften the blow. One example is the resolution of their son being kidnapped, another is the explanations of the husband's past (you kept waiting for something more to be revealed, but soon find that it was all there was). And then the tapes... This film defies all expectations of wrapping things up neatly, which might be off putting to some but does add to the overall experience in the long run. In any case, where the film truly succeeds is taking an unknown, external threat and exerting pressure on its characters, watching the honest pathos of a frightened and conflicted couple emerge.
