Nathan Weinbender reviews "A Wrinkle in Time."

Madeleine L'Engle's novel A Wrinkle in Time has been a kid lit favorite since the '60s, but it's only now made its way to the big screen. Director Ava DuVernay has taken on the planet-hopping sci-fi odyssey, and Nathan Weinbender says it's a refreshingly earnest children's film that works better in theory than practice.
