Judging from this trailer...
...The Sitter, starring Academy Award nominee Jonah Hill, looks like a stupid, raunchy retread of Adventures in Babysitting with the loutish, porcine Hill doing his usual loud moron schtick and for the most part, that pretty much sums things up. However, there is actually a little more depth and heart to the flick, though it doesn't maintain enough consistency in the laugh department.
For those who didn't watch the trailer - and why didn't you? - Hill is a tubby slacker who gets stuck babysitting for a friend of his mother's when he gets an offer of nookie from his fickle sorta girlfriend. Of course, the kids are punks - a mopey emo with "issues" (played by the kid from Where the Wild Things Are), a celebrity-obsessed girl, and an adopted El Salvadoran terror who spends half the movie blowing stuff up and relieving himself anywhere and everywhere - and hijinks ensue.
Where The Sitter actually scores some points is in making Hill not quite the disaster he initially appears, but more of an unmotivated victim of his own problems, which he eventually confronts and overcomes. Where it really gets crazy is when it pit stops in the crazy lair of a drug dealer (an unrecognizable Sam Rockwell) which is so genuinely weird that I don't even want to spoil the surprises in case you catch this sometime.
It's all meaningless and won't change your life, but if you burn 90 minutes on the couch viewing it, you won't wish you were dead. (There's some box copy!)
Score: 4/10. Catch it on cable.
Judging from the credits and the IMDB parent's guide, there's not much more that has been added for this "unrated" version other than a quick scene of two people shagging with a brief glimpse of bare breasts. While much of the vibe is sort of like Eighties teen comedies, there is no nudity in the regular cut; the R comes from the barrage of F-bombs. It's the 21st Century; how are we getting more Victorian?
