I was reading in The Sunday Times the other day about authors' reactions to bad reviews. The guy writing the piece mentioned his own experience, where he had written a scathing review of Graham Norton's autobiography. He received a card from Graham, not containing a diatribe of complaints; just a note saying "Cheer up, mate" and a CHEQUE FOR £500!
That's a pretty good way to deal with a bad review (if you can afford it). Mr Norton went up massively in my estimation. (Whatever one thinks of the decroded crap he fronts thesedays, time was when he was a pretty darn good stand-up. And his guest appearances in Father Ted were very funny.)
