i am an Outlander reader also, and while I was disappointed at things they changed/left out in the tv version, Discovery of Witches is so much worse, constrained as they are by only 8 episodes. I just finished reading the first book again just to keep everything straight. Saying the writers are putting the emphasis on the wrong syllables is the perfect way to put it. There was so much to put in that I suppose they did the best they could under the circumstances but to take that book and only give it 8 episodes is a disgrace. I think the development of the relationship between Diana and Matthew especially received short shrift.
Baldwin didn't come across as particularly menacing, as compared to the book, and if I hadn't read the book I would have no understanding of what daemons are.
I am hoping they do a better job with books 2 & 3.
