Gwyneth Paltrow plays a Nashville singing star whose career and marriage are both on the skids. Paltrow’s warm, supple voice is well-suited to plaintive ballads, and the other two actors trying out their pipes—Garrett Hedlund as her young lover and Leighton Meester as her fresh-faced rival—also acquit themselves admirably. But Shana Feste’s screenplay seldom rises above the level of daytime TV; the only actor who triumphs over her trite dialogue is Tim McGraw in a nonsinging role as Paltrow’s husband and manager. Feste directed.
