While that adventure boiled up out of a canceled date, The Sitter will follow a college student who gets suspended for a semester and heads back home to live with his single mom. He gets talked into babysitting "the eccentric kids next door -- two boys and a wild 8-year-old girl," and, I presume, something adventurous happens ... otherwise the comparison is quite pointless. Furthermore, this is not to be confused with that super-awesome sequel to the 1987 film that Disney is cooking up called Further Adventures in Babysitting starring Miley Cyrus and Raven Symone.
I'm thinking we'll have another Paul Blart, Observe and Report type showdown on our hands. But more importantly, what's more wild than a tween obsessed with Thor? (Hopefully not a barely-dressed, playing-mature 8-year-old.) Or a film with Elisabeth Shue as the wondersitter, and Keith Coogan, and Anthony Rapp as a horny teen? At least this one is doing it the right way -- take the base idea, run with it, and don't dare make it a sequel that could never live up to the original. ...if only others could follow this example.
That being said, I wouldn't mind seeing Maia Brewton pop up as the kids' mom or something.
