NB: I have not read the novels yet, but I'm afraid I'm going to be a little negative.
I had a “couple” of problems with this drama: firstly, I thought it felt a little 'empty' in terms of atmosphere. The camera-work, lighting and (to a lesser extent) the art-design was, for me, rather 'plain' - as if they were going for a very orthodox, no-frills adaptation of the novels. Likewise, I also thought that the soundtrack was rather dreary and 'safe' - although 'Tudor Pop' admittedly isn't my cup of tea. It would be nice - in general - if TV dramas would take more of a risk with their soundtracks: in the last week, I have re-watched Paul Thomas Anderson's “There Will be Blood” (with Jonny Greenwood's superb, experimental soundtrack) and then saw Birdman (which has a soundtrack almost solely composed of avant-garde jazz percussion) and was struck by how much these films were enhanced by a more original approach to background music.
If you're into period pieces, read on.
