Sex and the City author Candace Bushnell is penning two teen novels about Carrie Bradshaw’s adolescence. As a “Sex and the City” fanatic and Carrie-phile, I’m know I’m excited. I’m a 22-year-old who watched SATC as a teen, and I can tell you adults really underestimate the sexual knowledge of teenagers. But is this prequel idea too much of a good thing? Some think the movie went too far already. Has Carrie jumped the shark? Bushnell’s backtracking to the girls’ adolescent years could lead to SATC overload. For now, I’m torn, but either way I’m willing to bet I’ll be looking for the The Carrie Diaries in 2010, when I’ll be a 25-year-old reading a book about teens.
