The show delivers really well on emotional notes and the main actor fits really well in this role, I've seen in another show and I though he was alright but he really shines in this role, especially in one of the first scenes of the show where he has a breakdown.
The impending sense of doom and despair also creats a really cool and unique atmosphere which leaves you thinking about the show for days.
I've seen some criticism of the main couple but I feel given their circumstances their relationship makes sense and feels natural and the progression of it is pretty well done.
I also really liked that the main charecters were older, it just fit better with the vibe of the show but I also liked that one of the main charecters was a kid, like you would see him learn or realise something life changing and then imedietly remember that he would die in a few days and it just crushes you.
My main issue with the show is the ending, I really hated that they didn't die. Throughout the show whenever they hinted they might not die I was praying they would but they didn't in the end. It kinda makes everything till this now feel pointless and the second last scene where the kid blows away the meteor is awful.
But yea, aside from the ending, a really good show, defenitly worth it.
