'The Sitter' funny in parts but wildly uneven

The calibration is a bit off in 'The Sitter', David Gordon Green's comedy about a young slacker (Jonah Hill) tasked with minding three unruly children over the course of one insane evening.

Green aims to evoke 'Uncle Buck' and 'Adventures in Babysitting' – feel-good 80s family comedies from which the film freely borrows – while indulging in the same hard-R irreverence of his previous two films, 2008's 'Pineapple Express' and April's 'Your Highness'.
