As a production, it is good. Actors are very good, in fact. The only issues about this production would be the ending (last ~10 episodes or so). The plot drifted and seemed unfocused (after Episode 38 or so), even though I enjoyed watching the 3 main characters and their story lines unfold. It is really regrettable that the last 2 episodes seemed so fragmented for the characters. (I know there may be another season! And, that's good news indeed.).

The main challenge here is whether the plot follows character development. I personally feel like the three main characters' developments aren't explicitly shown to the audience. That's regrettable. There is a lot of change in their lives. They must be changing as people. But, it is unclear...
