I binged the first 4 episodes yesterday. My first impression is even better than the first two seasons. Harry is going to get real, real dark! Tense, interwoven plots, and there seems to be a conscious effort to develop the other characters (Edgar, Billets, Irving, Detective Robertson [who is not in the books], Harry's daughter) and give the show a little bit of an ensemble feel. I am a huge fan of the books, and at first I didn't like Titus Welliver as Bosch, since I'd always pictured him as a short, wiry guy.
