When its lead character speaks of “a jumbled mass of conflicting impulses,” she easily could be talking about writer-director Kenneth Lonergan’s sophomore effort, a lurching drama in which various coming-of-age incidents and more conventional familial friction get pressed up against an ethical dilemma that spawns an unusual wrongful death civil suit. More than a bit manic, Margaret is a film with as much distinct, wide-eyed personality as it has little focus. Not built for traditional catharsis or even really emotional engagement, it plays out as a string of thematically related acting scene exercises, and as such is a movie likely to be misunderstood by the few that don’t dismiss it outright.
