Sometimes, in these dark days for British cinema, it seems that almost every UK film is (unbelievably) worse than the last. Twenty years ago, this would have been dismissed as a cross between sex film and video nasty. Now, based as it is on a book by Martin Amis, and acted by a cast of semi-names including Olivia Williams and Paul Bettany, it's sadly part of the Brit mainstream. Ten dysfunctional people descend on a country house for a weekend of sex and drugs. All of them are loathsome, some fuelled with self-loathing and one a Satanist (of sorts) who intends to kill the rest. Vomit, rotting teeth, bleeding feet, crude sex and death are on the menu of a film that is never easy to look at and whose script barely exists outside its four-letter words. I haven't read the Amis novel, but it must be better than this.
