This film was controversial when it first appeared because of the fairly frank sexual scenes, although thy are mostly not real (apart from what seems to be actual oral sex at one point). But there is absolutely nothing erotic or unusual about them; they chiefly resemble farm animals mating in a mucky stable. Their coldness is deliberate, and an intrinsic part of this story about emotional chasms. Intimacy is what is missing from the character's lives. The overall milieu, which might be characterised as 'tatty-London' helps this a lot; the whole film is quite depressing in that sense. The least successful part of the film is the depiction of the relationship between Claire and her drama class student, which becomes tedious. The film is immeasurably helped by Timothy Spall's lugubrious taxi driver husband, at once knowing but also in denial.
