The problem with David Wain and co-writer Michael Showalter's Airplane-inflected spoof of corny American romcoms (in which New York is "almost like another character") is that it's often less funny than the movies it pastiches. OK, so the genre rarely hits the high notes of Manhattan or When Harry Met Sally, but with targets this broad (stupid meet-cutes; coffee-shop conversations; off-the-peg best friends; altar-dump weddings, etc), They Came Together really needs to do something more than just point and laugh at formulas we already know to be dumb. There are a couple of chuckles afoot as Paul Rudd and Amy Poehler recount their deliberately hackneyed tale to their increasingly uncomfortable best friends, but it's essentially a 10-minute sketch stretched out to an 80-minute movie, which feels even longer.
