Jennifer Garner plays Jenna, a 13-year-old girl who makes a wish to become older, and she finds herself thrust forward 17 years into the body of a gorgeous 30-year-old executive. Trying to discover what happened, she gets back in touch with her old high school friends, who've all lived 17 years of life, while she is still just a girl in the body of a woman.
The plot is obviously similar to the movie Big and all the critics have already bothered to point that out. While 13 Going on 30 isn't as good or engaging as Big, it's still a decent film with a nice message. The movie works a lot better than it should because of Jennifer Garner. She's funny and she has a great personality. It also helps that she's having fun in the role and it's so hard to actually hate her because she plays a very likable character. Mark Ruffalo gives an okay performance, he was a little dull though. I don't think comedy is his best genre. There are also some fun performances from Andy Serkis and Judy Greer.
The film was too cheesy and silly for me at times. For example, there was this one scene where Jennifer Garner is at a sleepover with all these little thirteen year old girls and she's telling them about her kissing experiences. After she does this, they all get up and start dancing. It was just so cheesy and annoying though girls will probably love that part. The movie is also pretty predictable. If you have seen the preview then you should know how things will end. The movie is pretty simple yet still entertaining. It's also a lot better than other similar films like Chasing Liberty and The Prince and Me. In the end, 13 Going on 30 is a decent, charming chick flick that should appeal to it's target audience. Rating 6/10
