“A Bigger Splash” (*1/2 out of four) was a listless melodrama about a rock star (Tilda Swinton) and her filmmaker husband (Matthias Schonaerts) whose vacation in Italy is disrupted by the arrival of her old friend (Ralph Fiennes) and his daughter (Dakota Johnson). Both Fiennes and Swinton are poorly used in a story of infidelity and lost love that turns out to be a big bore. Even the Italian scenery looks lackluster and drab. The Rolling Stones allowed several songs used to be used for key scenes and supposedly helped with the script for this but evidently time wasn’t on their side.
