Now, it's not a perfect movie, the subject matter is treated very lightly, but the story, the dialogs, and the characters are all very entertaining. It doesn't bring anything new, per se, to the table, but it does it with flair, and laughs. The girls are beautiful, but not plastic perfect. The acting is simple, but sincere and adorable in certain cases.
One of the scene, when they announce they're getting married, is the perfect example of the quality and tone of the film. It and its followup scene in the car are hilarious.
If you want to see a good little known teen flick with an adult mask, that would to it.
