Some of the content is interesting, it's just a shame that the book comes across as Ed Smith writing about how brilliant he is. Liked some of the content, that's a 4. But the smug, pretentious author and his writing were 2 so I've averaged out at 3, which feels generous. Its like no one ever knew having a point of difference, especially a left arm seamer, was effective until the great Ed Smith discovered it. C'mon man.
Spoiler alert: Ed Smith thinks he is an innovative and contrarian thinker and is not afraid to say so, many times.
