This book changed the way I view my own habits of consumption. I found his analysis of contemporary trends in consumption interesting and provocative. Also interesting was his conclusion that as people grow accustomed to the new means of consumption that they have to be continually impressed by something new. I thought his remarks on the architecture of the "cathedrals of consumption" were also very important. The most unsettling aspect of the book was Ritzer's comparison of modern styles of consumption with religious institutions, and even the conformity of religious institutions to this new means of consumption (i.e., the mega-churches of today). It was a good read, too, not too dense or pretentious. Very engaging.
