I havn't read all the thread yet but some comments show the old saying It's always best to criticise a programme if you haven't seen it!!!!
I, on the other hand, was apprehensive at the start but, by God, I'm glad I watched it all.
It was the first of a series and as such had to get the majority audience interested; which the bald facts of the history of the guitar would not have done, no matter how learned the presenter.
I got sidetracked by the link earlier to Jimmy Page and then by the normal process of time well spent ended up here.
Now this is guitar playing!!!

Have a shufty and get goose bumps like I did.
