I'm really enjoying it so far.
The dialogue is interesting - the Austen characters are speaking appropriate dialogue for their time period, and Amanda is trying to speak what she thinks is appropriate for that period, but it doesn't come naturally to her. The writers have brought in some of the original Austen dialogue, but they've also put in various pop culture references, and bits of dialogue from other Austen books, for example Amanda said to Bingley "it was badly done, Bingley, badly done" which is a direct lift from Mr Knightley saying to Emma "it was badly done, Emma, badly done" in Emma.
I don't like the Mr Darcy though. The book makes it very clear that he's so stand-offish because he's shy with people he doesn't know well and that doesn't come across at all in this version - he's just rude, arrogant and snobbish. I thought the recent Keira Knightley/Matthew MacFadyen film did a much better job of portraying his shyness, much better than the BBC drama did.
