The series was very intriguing. The human interest story is very riveting aided by the stellar acting by JK Simmons and Sissy Spacek. The themes portrayed like aging, grief, depression etc. are very relatable and they form a central component of the narrative - you almost forget you are watching a sci-fi. It was without a doubt one of the best TV series I've had the pleasure of watching lately. Just a shame that there won't be a second season.
