When it comes to credible depictions of small-town Pennsylvania, 'Groundhog Day the Musical' is about as veracious as a woodchuck named Phil is a qualified rodent meteorologist. This British import to Broadway - staged by people for whom small-town America is a typology, rather than a collection of souls - is more Whoville than Punxsutawney. Director Matthew Warchus' overstuffed and near-chaotic production is similarly far from Woodstock, Ill., the doppelganger for exurban insularity used to film the 1993 movie - a film forged in the caustic and improvisational Second City style by the late, great Harold Ramis, with Bill Murray as his melancholic muse. Andy Karl, the handsome, courageous and hugely talented star of these musical proceedings, is closer to the open-face sandwich that is Jim Carrey than to the iconoclastic Cubs fan Murray, benign and dangerous, perplexing and perplexed and a guy who looked like he'd been knocked around by the storms of life. But, you know, this is still a new Broadway musical that works - even one that has a few moments of greatness, replayed and redux.
