Finished the book and can summarise it as just awful!

I think your missing the point here , Lee admits his lack of academic background and gives us a book called "Off the Cuff" which represents his personal ramblings and anecdotes. To me this is more representative of a chat (down the pub) with the guy rather than polished prose through an overexhuberant ghost editor.

So put aside the moans and consider which approach is more representative of Lee's story.

It's not well written and poorly edited, as many have pointed out, with the many repetitions. However, given that neither subject nor writer have literary reputations they can be forgiven. I've read a lot worse, and I've got a degree in English literature! As an example , The Da Vinci Code has to be the worst 'thriller' written in the last 50 years, but they made ( an even worse ) film based on it!
