Undemanding road comedy which follows many genre rules, including the happy ending and the goo around family, and yet does so successfully. This is an entertaining, funny film, with well worked set pieces and some interesting characters. The dark elements of the plot are neither shirked or taken with any sense of gravity, so there’s a balance of sorts. The ending’s never in doubt and film hardly shouts for a sequel or imitators, and yet it’s a well-worked piece, played for laughs, with a good measure of slapstick thrown in.
