Director Saul Metzstein describes this 2001 British feature as “a comedy about a bunch of losers. . . . Thatcher’s children, people who are now completely apathetic.” Set mostly in a drab all-night cafe, it concerns four young people working graveyard shifts who spend their free time aimlessly chatting and debating whether or not they’re actually friends. The editing rhythms and artificial colors give a good sense of the late-night manic depression endured by these alienated laborers, but many elements seem contrived, from the car radio that won’t turn off to the girlfriend of a comatose hospital patient who takes advantage of her visits to have sex with the porters. 91 min.
