Overall I really liked this.
The cast has some familiar faces, which is instantly a plus for me.
I think I liked the first part a bit more than the second, and that's the reason I don't rate this a bit higher, but on it's behalf I gotta say that the show gives us several states of mind, emotionally speaking, from the characters and their journeys.
I also liked how they all connect in different parts of the main character's challenge.
A really touching and emotional last episode, almost entirely focused on those who stay and endure the pain of loss.
