I thought season one was decent, but wow, I really enjoyed last weeks episode, and this one was even better IMO.
The Sicily vacation vibe is spot on at all times, and the music couldn't be better suited for it. Cristobal Tapia de Veer is absolutely exceptional, and his music for both season 1 and 2 have both been gorgeous. The cinematography is also beautiful, some of the best I've seen this year. I noticed there's a lot of implied foreshadowing that works with the music to contribute to a darker tone, which I definitely like.
The writing is some of the best I've seen in a show in a while, in terms of characters and acting. The mystery of the dead bodies shown at the beginning of episode 1 has been very effective at keeping me in suspense, and with conflict coming from all directions it seems anyone could be the victim or the perpetrator.
Every actor does an amazing job at being funny, but also believable and complex. Despite the extensive cast, nobody feels expendable. I really like the performances from the actresses who play Lucia and Mia. I find them quite likable, and they have a really good dynamic as friends.
If this season keeps the momentum it has built throughout the first 2 episodes, I think it will sweep the Emmy's just like it did for season one. I couldn't be happier with the way it's going so far.
