The second movie for TV’s comedy queens threatens to become an ordeal, but finds its funny. Two squabbling sisters are flunking middle age – Amy Poehler’s Maura is a shy square and Tina Fey’s Kate a cash-strapped wild child – until they mount one final blowout at the family home. The preamble is laughless, however, and neither character makes much sense. Then, as Fey calls upon her resurrected peers to abandon their jaded adulthoods, the movie and party flip into the PC-be-damned joys of Animal House or The Hangover. The sisters fall out, the house falls down, and everyone gets really filthy. And a fat man on coke is always hilarious.
