I was a student political activist in the late 70's, I had friends who described themselves as situationists and I had a very basic understanding of what the term meant. So I when I read the reviews for this book, which was billed as "a readable explanation of the movement's ideas", I was really looking forward to it. Oh dear. This is a bumper book of obscurantist jargon, not odd lines but entire pages of incomprehensible drivel. Rather than genuinely trying to explain anything to the reader the author seems far more intent on demonstrating his own credentials as a situationist fellow traveller. I persevered to the end purely out of an amazed sense of curiosity - was Wark ever going to say anything useful, or failing that just comprehensible, about his subject? Well, not really. In an attempt to make sense of this book I frequently resorted to Wikipedia and to Googling various sources, all if which proved immeasurably clearer and better written. If you want to know about situationism I suggest you do likewise and save yourself £12. Potlatch my arse!
