It may be based on a true story, but “The Blind Side’’ delivers two heart-yanking hours of Hollywood physics. One kid’s bad existence gets better with the application of a great deal of upper-middle-class pressure. The movie recounts the story of how a tough-loving interior decorator named Leigh Anne Touhy (Sandra Bullock ) invited Michael Oher (Quinton Aaron), an enormous, athletic African-American teenager into her Memphis McMansion to live with her two children and adoring husband (Tim McGraw).
Leigh Anne is the unstoppable force. Michael is the immovable object. But as his grades improve and as he’s nudged toward a Division 1 football scholarship (he’s a natural tackle), Michael starts to open up. But we’re meant to believe that it’s Leigh Anne who does all the growing. Which seems about right for a movie built around Bullock. She is as entertaining as she gets here.
