The Roses (out Sep 4) is a comedically-framed tale of a married couple who, over several years, see their relationship disintegrate. The opening two acts are fun with witty conversations and shifting power dynamics. Stars Benedict Cumberbatch and Olivia Colman are great. Unfortunately, the closing half-hour lost me with its over-the-top, screwball comedy approach. Supporting characters also needed more to do. Grade: B-.
