I wasn't sure of the casting choices when announced, but overall I'd say they did a decent job especially with Dr. Scarpetta. I'm not familiar with the later books so a lot of the "present time" storyline and status quo didn't make sense at first but didn't take away from enjoying the series. The pacing and dual past/present storytelling reminds me of American Horror Story, so it wasn't as confusing or hard to keep up with as some people have stated as I'm used to that kind of production. The only things I didn't enjoy was the added focus on Dorothy, and that Pete and Benton didn't quite match their personas and descriptions from the books. There's of course some changes from the books and you can't please everyone, so it's not a "perfect" adaptation, but it's definitely an enjoyable watch whether you're a fan of the books or just coming into the world of Kay Scarpetta through the show.
