Not as good as the first season but gotDAMN it still managed to be incredible!
They totally went in with the over-acting and improv which can be off putting for some, but it totally works here.
The banter between Hanzawa and Owada was pretty much perfection. Their relationship reminds me of Batman and Joker- they absolutely hate each other BUT still need each other.
Kurosaki aka ball-grabber was another one that really stood out this season and I just enjoyed it every time he was on screen. Him being the only one who called Hanzawa by his first name just showed the love and respect that he had for Hanzawa- even though he "hated" him.
The casting director needs a raise because they did an amazing job at choosing the right people for their respective roles.

We had to wait years, YEARS, for this and I can honestly say that it was worth it. I personally wouldn't want another season, although the ending does leave it open for one, but would love a special or even a movie to end things.
Anyway I totally recommend this as I did the first season.
