Wow, an amazing ending, literally! Especially because not everything goes as you'll expect. I love this trait of this show.
Plot: this second season pulled back the trial of the case of the first season and a new (old) case. In this way the load of things that everyone had to face is doubled.
Everything is narrated in the same way of the first season: amazingly.
I'm sorry but at the moment I have no other words to describe it.
Acting & Actors: the more you watch this show the more you appreciate every character and every actor. They all are good. Some more than others, but everyone did a good job.
Soundtrack: very good, like in the first season.
Conclusions: this second season does not go under the level of the first one. If you liked the first season (like I do) I really highly recommends you to watch this too.
