I watched the first two on iPlayer in HD.
I was frustrated on two fronts:
Firstly the camerawork and editing was truly c**p. They went for a certain "style" that doesn't involve tripods nor proper focus, the lighting was bland, and the editing was rubbish too - clearly no sympathy for the subject matter, even if the cameraman had offered suitable shots. In many places the shots simply didn't match the voiceovers, and the cut away happened even before the comment had finished, never mind holding the shot so you could appreciate the detail being mentioned. All very annoying, given I'll never see the Gibbons carvings up as close as they could. Also there simply wasn't enough showing how it was done. Too many people going "Oh isn't Chippendale/Gibbons great!" and not enough of showing the detail of why and how things were done. There are good cameramen out there. Why not use someone good?
Secondly, on a personal note, There were so many "wow, I could have seen that!" moments. The Cosimo Panel we didn't see in Florence (OK, you need about a month to get round everything), and I used to play rounders in Petworth Park as a lad, but never visited the house. And, to add insult to injury, last year (2011) we were in Galloway, but missed Dumfries House - how did that happen??? Spot the long-term *****!
Anyway, despite my irritation with the style, I'm glad the series has been made though. It was just about good enough to catch the interest of a new generation, and perhaps it has done so.

PS: Contrast it with that RTE series on crafts - the Cavan furniture builders and the boat builder - far better made with a pace and style that suited the subject.
