Many passages felt too slow-paced especially in the 1st and 2nd episode. On the other hand, I found Connie, Hilda and most of the other cast lived up to the characters I had imagined as a reader. Many lines of Mellors and Connie were taken straight from the book which was good. The pheasant chick scene was well portrayed. The sex scenes were not as gratuitous as happens so often on screen. In this case they are part of the story and were tastefully done on the whole. Contrary to some of the above comments, I think the series went quite far enough so far as sexual explicitness was concerned. What is acceptable in literature can easily become voyeurism when depicted on screen.
Sean Bean is a favourite actor of mine but I was disappointed with his impersonation of Mellors. I recall Mellors as a very proud man looking down at Sir Clifford in spite of his subservient position and I'm not sure Bean expressed this sufficiently. For instance he was good in his confrontation scenes with Connie or Hilda but played Mellors as too humble almost downtrodden before Sir Clifford and Mrs Bolton. Also in the book Mellors switches from dialect to standard English and back according to the situation and I felt this was not so much in evidence in the series.
My main disappointment however is the new glossy happy ending which is far too easy and banal. It seems at odds with the questions raised by the novel notably about the feasibility of relationships between social classes.
