This limp sequel to the hit 2003 comedy sees Steve Martin reprising his role as the daddy of the 12-strong Baker brood, who revives an old rivalry with ultra-competitive neighbour Eugene Levy - also the father of a sizeable horde of kids - during a summer camping vacation. Though the children get on, that doesn't stop the two posturing dads from a spot of macho one-upmanship when a "friendly" competition is arranged between the respective families. Cue lots of tired and obvious slapstick scenes. Youngsters may find one or two moments worth a titter, while Bonnie Hunt as Martin's stoical wife delivers all the best dialogue, what little there is. However, grown-ups may be surprised at the under-use of Martin and the misuse of American Pie stalwart Levy, who's great at playing quirky characters but not so hot at being downright obnoxious, which he is here.

Steve Martin and Bonnie Hunt return as heads of the Baker family who, while on vacation, find themselves in competition with a rival family of eight children.
