This YA adaptation with Zoey Deutch as a popular girl in a time loop of life and death has sincerity and style Bill Murray may not be around to wisecrack, but Zoey Deutch shows plenty of versatile, captivating teen turmoil in the “Groundhog Day”-like scenario that is “Before I Fall,” the latest beloved YA novel to get the glossy big screen treatment. With a construct that has a popular high schooler mysteriously reliving the same turbulent and invariably tragic day over and over, director Ry Russo-Young and screenwriter Maria Maggenti find plenty of sincere emotion and stylish suspense amidst the melodrama and expected platitudes.
