Adam Sandler's got a winning formula -- lowbrow yuks plus sentimentality equals box office gold -- but critics say Jack and Jill may test the patience of even the most loyal of Sandman acolytes. Tarsem Singh certainly has a knack for eye-popping images, but critics say the problem with Immortals is that its attention to blood-soaked visual detail always trumps character development and storytelling. J. Edgar purports to explore the professional and personal life of influential (many would say too influential) FBI Director J. Edgar Hoover, but critics say Clint Eastwood's admittedly handsome biopic is ultimately too vague a portrait of its controversial subject.
