“The Glass Castle” is a far better book than movie. While this is not surprising on its face, since books are often more complex, moving and involving than their screen adaptations, it is astonishing for other reasons. The cast is topnotch. Oscar winners and nominees abound. Director Destin Daniel Cretton adapted Jeannette Walls’ bestselling 2005 memoir of a turbulent and destitute upbringing. His previous directorial effort was 2013’s “Short Term 12,” a deeply moving and credible drama about at-risk kids.
