“A Bigger Splash” is simultaneously sumptuous and startling — a true feast for the senses, featuring four superb performances from Tilda Swinton, Matthias Schoenaerts, Dakota Johnson and especially Ralph Fiennes. He absolutely tears up the screen as well as the film’s idyllic setting on an island off the coast of Sicily. Director Luca Guadagnino’s follow-up to 2009’s “I Am Love” isn’t quite as gorgeous or great, but then again, what could be? My RogerEbert.com review.
