Morgan Freeman is a widowed writer whose summer escape is interrupted by a single mom (Virginia Madsen) and her three daughters. Predictability ensues.It cannot be easy of late being Rob Reiner. Largely pushed out of the picture in the recent memorial accolades for Nora Ephron (it was he who directed "When Harry Met Sally …," after all, from Ephron's screenplay), usurped by Christopher Guest as maestro of loose-limbed satirical comedies, Reiner has shifted from making studio films to gentle, small-scale indie movies — a trajectory that would have seemed unlikely judging from his 1980s résumé, which included "This Is Spinal Tap,""The Princess Bride" and"Stand by Me."
