This neatly executed mystery is just the sort of thing Hollywood craves from Steven Soderbergh: genre entertainment as cool, clean, and impersonal as a Formica countertop. Rooney Mara plays a young woman suffering from depression after her husband returns home from prison, and the other above-the-title stars are all Soderbergh veterans: Channing Tatum (Magic Mike) as the husband, who’s done time for insider trading; Jude Law (Contagion) as the wife’s psychiatrist, who persuades her to try an experimental drug; and Catherine Zeta-Jones (Traffic) as her former shrink, who knows more than she’s saying. The plot twists are expertly handled, which is a good thing, because the movie doesn’t offer much else.
