This is an enjoyable book for fans of Judge Dredd, 2000AD and the "Brit Pack" group of writers who have emerged from that comic over the past 20 or so years, but contains very little insight. It is far too preachy for its own good, and the writer, while obviously having great affection for his subject matter, clearly hasn't read that much of it.
For completists of Dredd paraphenalia only. Judge Dredd: The Mega History is a far more worthy tome for academics to get their teeth into.
