This show, right from the first scene all the way to the last, was amazing. I am so sad it has ended. Not one performance was bad. The casting could not have been more spot on. Everyone was very believable in their characters.
The script was fantastastic. I did feel that some episodes fell back a little. They felt a bit like filler episodes where not much happened. This was only a few episodes in the second season. But overall, I found that the majority of episodes as a whole, had purpose and wasn't lacking at all. I really wish it didn't have to end. The only comparable show I would say is The Newsroom, which I found slightly better, more so to do with the pacing and writing. But this is definitely in the same field.
