Bravo, Clint Eastwood! With “Jersey Boys,” the director moves away from his sometimes schlocky and often manipulative movies such as “Invictus,” “Gran Torino,” or “Hereafter,” and gives us a biopic as moving as it is entertaining. Like the Broadway musical, it’s a story of greed, success, fall and redemption, none of it unpleasant as the protagonists are young, gifted, and for the most part naïve.
