Cate Blanchett and Judi Dench in Notes on a ScandalNOTES ON A SCANDAL

In Richard Eyre's Notes on a Scandal, Judi Dench appears to be having an amazingly fine time playing an evil harridan. Why does the movie itself have to be such a dud? In the film, Dench portrays prickly history teacher Barbara Covett, who becomes pathologically obsessed with Sheba Hart (Cate Blanchett), a younger colleague in the art department. (As Barbara's last name suggests, Eyre's film, based on the novel by Zoë Heller, won't be much concerned with subtlety.) When Barbara discovers that the married Sheba has been carrying on with a 15-year-old student (Andrew Simpson), she uses the knowledge to surreptitiously gain Sheba's trust, in the hopes of turning their friendship into something more, shall we say, Sapphic. Subsequently, threats are made, careers are jeopardized, relationships are destroyed ... and why oh why isn't the movie more fun?
