But some sex scenes are defining moments in cinema. It is not very explicit, or even protracted, but like the rest of the film is almost unique in that it is unembarrassed about celebrating sexiness, unencumbered by guilt or dramatic doom, and reclaims the sex scene from male-centred eroticism. One of the most extraordinary sex scenes of modern cinema takes place between puppets playing heterosexual characters, and the very fact of their being plastic liberates the film-makers to make an explicit sex scene in ways that would be quite impossible with flesh-and-blood humans. In effect, a sex scene in two parts, an interruptus that might in other circumstances be intended comically — comedy being the great undeclared enemy of eroticism. This sex scene is almost outrageously humid and overwrought.
