I wasn't sure what to make of it at first. A late night choice. It was a strange concept of undersea people, and an undersea town, but the story works very well. More so, the character development is some of the best I've seen in a long while. Keeps you guessing too, which is refreshing with so many shows becoming formulaic. Planned to only watch a couple episodes, and was surprised how quickly scenes became memorable. A little sad to see it's a limited series.
