At least according to various British notables, yes.. I don't know who all these people are, but the commentary is often amusing; cf. Jonathan Meades on J.K. Rowling ("the sub-literary analogue of Tony Blair"), Johann Hari on Martin Amis ("a disgusting, malformed, literary dwarf"), Jah Wobble on Mein Kampf ("as interesting as reading a bus timetable"), or Ian McKellen on Leviticus ("full of old legal nonsense that some people still take seriously"). I also find it kind of amusing to see A.S. Byatt diss someone for "sickly eroticism", and then have one of her own books dissed as "a kind of schmaltzy Mills & Boon romance dressed up with cod Victorian poetry to make it seem more profound". Literary feud! Literary feud!
"A sinister cabal of superior writers."

A lot of the comments tell you far more about the person than the 'worst book'. For instance, Brian Sewell (The arts critic for the London Evening Standard) on A Brief History of Time tells you nothing about the book, but is a complete summation of everything you need to know about Brian Sewell.
