Sonny with a chance

(New series )

Demi Lovato, 16 year old Disney princess, stars in a broadly cute sitcome that fits nicely into the channel’s cartoon-bright stable of shows. She’s Sonny Munroe, who found online celebrity with her comedy videos and now has come to Hollywood to join a kids sketch show, So Random! As a performer, Lovato is the happiest of campers, eager to please and brassy- reminiscent of Kathie Lee Gifford but younger and minus Hode Kotb. Sonny clashes with Random’s big star, Tawni (Tiffany Thonton), but the more entertaining plot focuses on the cast’s rivalry with MacKenzie Falls, a drama about rich kids shot on the adjacent set. Falls looks like a community theater Gossip Girl. That’s meant as praise
