Owen Gleiberman of "Entertainment Weekly" gave the film a very positive review with a grade of "A-", writing "13 Going on 30 is the rare commercial comedy that leaves you entranced by what can happen only in the movies." Gleiberman also praised Jennifer Garner's performance, writing: "She cuts out all traces of adult consciousness, of irony and flirtation and manipulation, reducing herself to a keen, goggle-eyed earnestness that's utterly beguiling." Mick LaSalle of the San Francisco Chronicle wrote: "The possibilities of Jenna's confusion are exploited for full comic effect. Garner, who turns out to be a charming, abandoned comedian, makes Jenna's incredulousness and innocence very funny and occasionally even touching." Joe Leydon of "Variety" also praised her performance, writing "Garner throws herself so fully and effectively into the role that in a few key scenes, she vividly conveys Jenna's high spirits and giddy pleasure through the graceful curling of her toes." Leydon praised the director Gary Winick for "bringing a fresh spin to most of the script's clichés and emphasizing nuggets of emotional truth provided by Goldsmith and Yuspa." Wesley Morris of "The Boston Globe" wrote that "The movie is tailor-made for women who openly lust for dream houses, dream jobs, and dream hubbies." He also wrote that "the best stuff involves the childhood preamble. (The young actors playing Jenna, Matt, and Lucy are terrific.) Those moments feel painfully, comically true."
