Most critics lean the same way: 13 Going on 30 is a frothy, good-natured romantic comedy that nobody mistakes for anything more, and the praise clusters almost entirely on Jennifer Garner. Review after review finds her guileless, energetic and funny, and several say she is the reason the body-swap fantasy works at all. A few also warm to her awkward chemistry with Mark Ruffalo, and the later notices, written years after release, are the fondest of the lot.
The reservations are about everything around her. The premise is called derivative, the plot predictable, the magazine-publishing subplot overlong and full of holes. The sharper dissent is over what the film is saying: The Guardian objects to the idea that grown women secretly want to behave like children, and Slant finds its picture of a happy life narrow and contradictory. The spread is fairly wide, from warm to hostile, but the bulk of the reviews settle in the middle.
