It was refreshing seeing a con film again. As it is, it is quite light, and there is hardly anything I haven't seen in it, but does being pleased necessitate a constantly churning wheel of brand new things? It's a fun hour and forty-five minutes of standard con mechanics, and if you like con mechanics you will be delighted.
There is a point where you will find yourself surprised as the tone the film suddenly takes and controls well. Another thing it controls well is its handling of its twists, for there are always twists and mentioning their mere presence is like mentioning Spider-Man's presence in Spider-Man 3. The twists are interesting in that they feel predictable or that they're taking the simple way out, but that is never for certain.
Michael Serrault is the film's great highlight. He is tremendously likable and infectiously dry, and his occasional physical timing or subtly crisp one-liner holds the film's smiling side at bay amidst some token moments of comic relief, namely the presence of the gaudy widow whom Serrault constantly must try to hide from. And of course Huppert, as the film's real star, is truly perfect as a con woman, a 100% confident seductress, the fleshed out realization of the practically imagined version of a con woman. She does not stand out nor is she below par, even if she is upstaged a wee bit by Serrault, because she even characterizes her character's elusive quality.
