I saw Wurtzel in conversation with Ruby Wax, Bret Easton Ellis and Carrie Fisher on a TV show here in the UK, and in comparison to those three she came across as dimwitted, shallow, and with nothing of any real worth to contribute...she also seemed to talk only about herself. I was distinctly unimpressed with her, as as such have avoided her books because she struck me as the classic 'all hype, no substance' media darling.
Which reminds me I've got to pick up 'Lunar Park' sometime soon....
