“La La Land” (*** out of four) was pleasant fluff about a jazz pianist (Ryan Gosling) who falls in love with an aspiring actress (Emma Stone) and how their careers take them on eventual different paths. Not a great film as many critics have said but an overall affectionate homage to musicals from Hollywood’s Golden Age. Music score and numbers are hit-or-miss but Gosling and Stone’s chemistry and camaraderie (in their third film together) make this entertaining. Opening and closing scenes are terrific.
