So far, soooo creepy, like the proverbial frog sitting in a pot of black goo, being brought to a low simmer, and realizing too late that the pot has come to a roiling boil... Gritty, grimy and atmospheric, infectious, like an improperly dressed wound, one may need some antibiotics, (or a VERY HOT shower) before this is over.

With an approach close to "The Shining", by Stephen King, the best thing about this series is the creation of an unhealthy atmosphere, to build around the building a kind of entity with its own life that keeps its inhabitants inside. In this description of isolation and mental control, various interpretations can be found, from the reference to a latent Nazism, which directs the inhabitants of the complex, to the representation of a modern society in which coexistence is not synonymous with personal relationships. The series achieves more values in its aesthetics, in that disturbing atmosphere that surrounds the malefic building, than in the development of the story, sometimes lost in some of the characters and parallel stories, but it builds an interesting sample of psychological terror that is growing slowly.
