FROZEN 2 (2019) Stream on Disney Plus; rent on Amazon, Google Play, iTunes, Vudu and YouTube. Over the weekend, Disney released this “Frozen” musical sequel to its streaming service months ahead of schedule, in what the company described in a statement as an attempt to provide families “with some fun and joy during this challenging period.” Whether or not parents will welcome the prospect of their children getting “Frozen” songs stuck in their brains is probably an open question, but those hunkered down at home may well take solace in a virtual escape to Arendelle, the picturesque kingdom where the movies take place. The sequel reintroduces Anna (Kristen Bell) and Elsa (Idina Menzel), the monarchical sisters at the series’s center, whose new story is set into motion when Arendelle falls into crisis. “The ensuing adventure is lively, amusing and predictably predictable with revelations, reconciliations and some nebulous politics for the grown-ups,” Manohla Dargis wrote in her review for The New York Times. “It’s never surprising, yet its bursts of pictorial imagination — snowflakes that streak like shooting stars — keep you engaged, as do Elsa and Anna, who still aren’t waiting for life to happen.”
