As long as you turn your brain off and don't think about anything too hard, and you're not part of any of the groups that she openly mocks (e.g., too fat, too thin, gay, overly feminine, not feminine enough, not English, not the right kind of English, etc.) you can read her books and have a good time. They're like Asylum films with a higher budget. Good is a hell of a stretch though.
