I'm no expert on parenting, but rather than forbidding children and teenagers to indulge their curiosity or base interest in stuff like Twilight, I'd seek to ensure that they were also presented with alternative examples and messages in the form of other fiction, real relationships, subtle parental guidance, and so on.
Oh, absolutely. One mark of successful parenting of young girls today: you have a teenage daughter who has no interest in Twilight
, or, if she must
, enjoys it on an appropriately mature and sardonic level. If, on the other hand, you have a daughter, especially aged 8-14 or so, who actually thinks it's a work of art, and not a juicebomb
, well... some remedial parenting may be in order.
