Time Out says
This Nickelodeon production may be designed for short attention spans, but must the characters have them as well? After her little brother (Jackson Nicoll) goes missing on Halloween, Wren (Nick TV actor Victoria Justice) and her bestie (Jane Levy) do what anyone would do: flag down two car-possessing nerds and crisscross Cleveland in pursuit. Detours involve a fake gunfight at a fast-food joint; crosscuts to Wren’s brother and a convenience-store clerk pulling pranks on Cleveland’s biggest bully (Johnny Knoxville); and the imperilment of an asthmatic cat. Adventures in babysitting needn’t be less wacky, but John Hughes’s sense of craft might have helped Fun Size earn its titular adjective.
