It is quite clear from very early on that this is a very thinly veiled deconstruction of the X Factor machine. The judges in the fictional show are too close for coincidence (albeit that Sharon Osbourne is replaced by a trans-sexual Ozzy for a bit of a difference). Most of the story is about the mechanisms of choosing and promoting contestants and ultimately deciding who wins.
There are, of course, Elton trademark oddball characters and dysfunctional love lives but this book is more concentrated on the subject - the Chart Throb reality TV programme - than any previous Elton book. Because it's not a who-dunnit, Elton had to come up with a twist at the end and this is the weakness. The twist is somewhat contrived and frankly didn't enhance the book in any way.
Ben Elton fans will recognise the fairly easy-read style that gets the point over without stretching the reader. Not as gripping as Dead Famous for instance but still worth a read just for the insider info on X Factor. Should be mandatory reading for anyone thinking of applying to the show.
