It's a pretty fair critique, but for me the good in the book still far outweighs the bad. With such an immense project and with so much information to cover, I fully expect there will be the occasional factual error or instances where the author draws a conclusion or makes an assumption that isn't totally accurate.
Ultimately, as much as I may love it, we're talking about the making of a TV show
here. It's not a history of the Civil War or the Lincoln presidency or anything.
I don't know that I agree. The same critiques are applicable to a lot of self-published books. I recently purchased an 800 page book about the history of Atari and you could copy and paste just about every criticism Harvey raised for TATV to that book as well: too long, spread out needlessly across three big volumes, no index, poorly written, poorly edited, nominally proofread, and, worst of all, rumor and supposition passed off as fact.
That's what's so disappointing about books that purport to be THE history yet wherein the authors can't be bothered to apply critical thinking to the work. If I need to fact check the book that is supposedly the facts, there's a problem.
