It is incredibly difficult to write a review about political, important issues. Any opinion of the book will include at least some opinion of the reviewer's. Here's my attempt at helping you choose how to spend your big check signed by a faceless corporation.
Michael Moore came to my attention when he was using the corporate chicken to poke the underbelly of the corporate/government leadership. Unsurprisingly, the show was hilarious to some and to others the equivalent of ripping off a band-aid (which should be capitalized but considering the subject I chose to have my own rebellion against corporate tyranny... go me!) Those he skewered onto his kabob just hated it... and him... and all of the O2 that enters his body. I would definitely not wasn't to be one of them.
This book is just as funny; just as serious; just as foundation shaking for the reader. Moore uses as his literary tool some uncomfortable points of a very sharp pen. Readers be prepared.
I read this when it was published (bought the hardback and everything. go me!) and have not revisited it since then. His strident tone will be the same but I suspect that a reread would show that at least some of his opinions have become more common than when this book was written. He has influenced so many on the "right" and "left".
Moore's great talent is best enjoyed through his films, but the book allows both reader and author time to digest and meditate about the issues Moore wears on each arm. Subtlety is not the author's forte in this book any more than in his other work.
My suggestion is this: read the books. Watch the movies. Give Moore's opinions a chance. If you agree with him that's OK. If you don't agree then write your own book... and read this one for background. ( )

Good agitprop, classic Moore ( )

The author approaches life with his characteristic humor and sarcasm, but some of his rants fall short of the mark in this particular book. ( )

Downsize This could have become out of date very quickly had everything Moore suggested been implemented. Moore gives a lot of information and makes some humorous suggestions. The book seemed to go on and on without really saying anything new. Maybe this is why by the end of it he did away from corporate America theme and starts talking about the O.J. trial. Isn’t this just what the media did, ignore the major issues of the day for the sensational one. Michael Moore isn’t the funniest commentator, but he does discuss something very important. For this reason alone, Downsize This is worth reading. ( )

Unashamedly anti-rightwing, this is an eye-opening account of what is going on in the US and Michael Moore's proposals for fixing things.
