Yay an Emma shout-out on top of the Persuasion one. I definitely liked the Book 1 part the best, but I'm also not much of a mystery reader anyways. I'm glad Lydia's portion was pretty insubstantial for most of the book, because I had forgotten how *annoying* she is. 
 There were a few things I didn't enjoy just because of my preconceived notions of the characters, and then a few things I didn't like because of the writing. Of the latter, it was mostly just the very exposition-y bits about the various portions of a murder trial in Napoleonic Wars times. It got a little boring. Also, so much of the description seemed to be so obviously for the "modern reader" to explain why they couldn't do things the CSI way. Not that I would expect them to, hence finding it a little over-explained. I did find the little segue on the lack of appeals process interesting, but only in the trivia sense. 
 For the characterizations, I always though Colonel Fitzwilliam was fairly pleasant and non-offensive, but he was really douche-y in this book. It wasn't a huge deal, and by the end of the book I was just used to thinking he's a generally pompous guy, but it was jarring at the beginning. Also the thought of him with Georgiana (not a spoiler) is squicky. One that did make me sad was the little side-note on Charlotte. I really liked Charlotte in the original book, and I always assumed that after Elizabeth's visit that Elizabeth had a better understanding of how Charlotte could resign herself to a life married to Mr. Collins. And in my head I imagined that they went back to being good enough friends that they would write often or something. So it was a little sad to read that Elizabeth never trusted Charlotte again and suspected her of deviousness/mischievousness in telling Catherine de Bourgh about the non-engagement. 
 Overall I don't think the book ruined any of the legacy of Pride and Prejudice by any means. I liked reading about the continuation of the lives of the Darcys and the Bingleys, that was the best part. Near the end, I did feel that the narrative focused much more on Darcy than Elizabeth which is a bit of a change from the original. The tiny little clues and side story threads that were planted did get a satisfying payoff in the end. And I totally didn't guess at the actual solution.
