It's too tempting to wag a feminist finger at Bynes' go-girl ''find yourself'' Cinderella story. Her long-lost dad is, conveniently, a rich British lord who, natch, wants to give her a makeover! She shakes up his fuddy life...by taking him shopping! And ultimately, what she really seems to want is a cute English boyfriend. Firth (he who played Mr. Darcy!) embarrasses himself (yes, he air-guitars in front of a mirror), and Bynes, though likable, is merely Sandra Dee dressed up in belly-baring low-riders. Still, the tweens love it. And it's just a cute little movie -- right? EXTRAS A game in which you re-create Bynes' various outfits trumps her chirpy, I-love-everybody commentary.
