Love and loneliness are the themes of Mike Leigh's new film - like many of Mike Leigh's earlier films. The scene, too, will be familiar: a Greenwich housing estate, surveyed with Mass Observation detail, over one ordinary weekend. It holds you. Even its opening minute or two, when nothing happens, no one speaks, holds you. A fat teenage girl mops the corridor in an old people's home, wrapped up in herself, perhaps a little too intense.
