Query: Overrated fluff. Nothing original at all.

This book was a severe disappointment. It's a well-known strategy book with an catchy title and reasonably compelling reputation. This was my second time reading it, after throwing it away in frustration a few years ago. Opening up vast blue oceans of opportunity - who wouldn't want that? Unfortunately, it falls far short of the hype. Another reviewer described it as "fluff" - they are correct. The book is full of vague theorizing, with little in the way of an actual framework to think about strategy. Nor are there significant insights from successful thinkers, which would have been valuable in lieu of a framework. If you have even a basic amount of business knowledge and some experience to match, this book offers very little. Stay away - your time and money are better spent elsewhere.
