Jennifer Garner glows like a rising star in 13 Going on 30, a girly version of the Tom Hanks classic Big. Jenna (Garner, Alias, Daredevil), a frustrated teenage girl, just wants to skip past all those annoying adolescent years and arrive at a glamorous adulthood--and thanks to some inexplicable wishing dust, she does. But once she reorients herself to a life as a high-end magazine editor with a sports-star boyfriend, she discovers that in the 17 years she skipped she became a not-so-nice person, including casting aside her best friend Matt (played as an adult by Mark Ruffalo, Eternal Sunshine of the Spotless Mind). There's no question that Jenna will rediscover her lost innocence, but Garner rises above the lack of suspense. 13 Going on 30 floats along, buoyed by her goofy sweetness. Her lovely looks are made accessible by her unfettered silliness; it's a winning combination. --Bret Fetzer
