One can easily pick apart this Jane Campion adaptation of a thriller by Susanna Moore: it isn't very satisfying as a thriller, and certain details—like the heroine assigning Virginia Woolf's To the Lighthouse to her inner-city high school students—come across as just plain silly. But I still consider this the best (which also means the sexiest) Campion feature since The Piano, featuring Meg Ryan's finest performance to date and an impressive one by Mark Ruffalo. Scripted by Moore and Campion, it takes on the unfashionable question of what sex means for a single woman drifting into middle age, and what it says on the subject veers from the obvious to the novel. Campion is better with moods than with plot, and her capable handling of some actors (including Jennifer Jason Leigh and an uncredited Kevin Bacon) ameliorates the hyperbolic characters they're asked to play.
