“Shut In” (*1/2 out of four) was a ridiculous psychological thriller starring Naomi Watts as a widowed child psychologist whose husband was killed and her son seriously injured in a car crash and who now lives an isolated existence in rural New England. In the midst of a deadly storm, she attempts to rescue a young boy but old secrets from the past threaten their existence. This progressively dumb and ugly thriller should have been “shut down” before filming began. Final plot twist 3/4 of the way through is laughable. Watts is far too strong an actress for this weak material.
