Marketing people such as Laura Groppe, president of Girls Intelligence Agency, said that the timing of the release of "Metamorphosis" and other Duff-related products was right because there had been a lack of teen idols since Britney Spears, and that Duff "not too pretty. Not too thin. Not too anything ... like a little Meg Ryan." According to Marketing Evaluations/TvQ, Duff was, in July 2003, the female star most popular with kids aged between six and eleven. Amy Doyle, at MTV's vice president of music programming, said Duff was "definitely one of the hot people to watch ... She's become the fabric of pop culture with teens right now." There was concern from some, however, that Duff could become overexposed, although Duff's manager emphasised his selectiveness against "[if something looks cheesy", and that Duff "doesn't want to be all over TV commercials". Others, such as Robert Thorne, the CEO of the Olsen twins' Dualstar Entertainment, said that Duff should have stayed with The Walt Disney Company — from which she separated after contract negotiations broke down — to build the "Lizzie McGuire" franchise and use it to help develop her career into adulthood. In spite of this split, the profile of Duff and the album was supported by the DVD release of "The Lizzie McGuire Movie" and reruns of "Lizzie McGuire" episodes on the Disney Channel for two seasons. Duff herself said that "Lizzie McGuire" was "a great place to begin my career", but said that "it's exciting to go out on my own" with "Metamorphosis".
