This universe is quite exciting and fascinating, I wanted to know what happens next and what is the mystery behind. The aesthetic representation of the buried city is successful, in simple and evocative settings, with an industrial tendency, as is the opening credits music. The narration involving different periods adds richness to the storytelling. Rebecca Ferguson is quite interesting in her physicality. On the downside, the mise-en-scene is completely ordinary and basic, as is the dialogue. I was bored and skipped some conversation scenes. A worthwhile series on the whole, although not achieving excellence.
