“Yet for all his fidelity to the Broadway source, Clint Eastwood has made a Jersey Boys movie that ultimately differs from the stage version in several key respects. It’s an altogether moodier, more real, edgier piece of work, more Bird than Bye Bye Birdie, giving equal weight to the personal tragedies of Frankie Valli and his bandmates — busted-up marriages, estranged children, embezzlement scams and dangerous entanglements with the Jersey mob — as to their professional triumphs. Onstage, misfortune was frequently softened by the show’s overarching uptempo mood. But onscreen, Eastwood hits as many blue notes as four-part harmonies.” — from Scott Foundas‘s 6.10 Variety piece on Eastwood and the film.
