The opening of The Beguiled is lush on every level: Mist hangs in the moss-draped trees as a young girl goes out mushroom-picking, her singing underscored by an uncanny low rumble. We’re in the Civil War South, so that rumble must be battle, a muffled sound that barely intrudes on the idyllic scene. This is director Sofia Coppola in signature mode, creating voluptuous sights and sounds that disguise a serious deficiency of ideas. The Beguiled may be the most inert of Coppola’s films, a vapid cruise through an isolated hothouse. Along with its other shortcomings, it’s not nearly as interesting (and nowhere near as perverse) as the 1971 film that precedes it, directed by Don Siegel and starring Clint Eastwood.
