Runaway Vacation (PG)

Runaway Vacation is a family comedy about an overworked businessman (Robin Williams) who takes his reluctant wife (Cheryl Hines) and two kids on holiday in a mobile home which is larger than a U2 tour bus. It's much less repulsive than the equivalent Steve Martin fiascos. But it's still a road movie that never gets out of second gear. Williams and co have a mishap with a sewage pipe, they fight off a raccoon, and they share a camp site with a clan of folk-singing trailer trash led by Jeff Daniels. But so what? Most of us have more eventful holidays than that every year.
