Unfaithful is Adrian Lyneís typically glossy updating of Claude Chabrolís La Femme Infidele.Diane Lane is superb as the New York housewife with a loving husband (Richard Gere) and precocious son (Erik Per Sullivan) who embarks on an affair with a French book dealer, Paul (Olivier Martinez). She meets Paul by chance but he flirts with her and makes her feel sexy, and itís enough for her to childishly abandon her adult inhibitions.
The set-up - and first hour or so - of Unfaithful is believable and compelling. These are mature people conducting an affair that didnít begin for contrived reasons. But the film unravels badly when Gere wises up and decides he has to assert his masculinity in response. Unfaithful becomes a stupefyingly inept thriller as ludicrous turn follows ridiculous twist. All empathy for the characters is lost.The poorly conceived and infantile second half all but erases the memory of an intelligent and well-realised opening.
