Screenwriter Max Werner and director Josh Schwartz clearly have several well-worn copies of Adventures in Babysitting between them, but they keep the gags coming at a brisk pace.
A modern day revamp (of sorts) of the 1980s teen classic Adventures in Babysitting meets The Hangover for tweens, the feature debut of television writer/producer Josh Schwartz is a mess of a movie.
Justice makes a likeable lead but director Josh Schwartz's comic touch is distinctly leaden and a high proportion of the would-be funny scenes - some of them involving an uncredited Johnny Knoxville - fall flat.
This is a dog's breakfast of a film, lurching from simpering teen-romcom sentiment to off-colour paedophile gags to sub-'Juno' hipster cultural references to a lecture on the woes of single motherhood without breaking stride.
