While The Silent Sea isn't a groundbreaking space thriller, I think it was very well done and a very entertaining watch. The moon renderings were gorgeous and realistic looking, and the story is interesting and pulls you in quickly. The cast is star-studded, with Gong Yoo at the helm in one of his most gorgeous looks yet, and most of the time he's just wearing a space suit! Acting is great across the board, the mystery of the lunar water is very cool, and the show set up for a great second season (please let us get a second season!)
Personally found this to be very entertaining and a great binge watch!
