Good episode.
River was always interesting and I’d like to see more done with the character.
The spouse has “It’s A Wonderful Life” playing. I’ve been watching something much more enjoyable - Ironside Season 2.
Dr Who is an oddball. Being sci fi it obviously tends toward the secular but occasionally they will throw Christianity into it in a good way.
In this episode “Gridlock” the entire population of New New York planet sing “The Old Rugged Cross” together every day.
