The incorporation of directors such as Kim Jee-woon or Yeong San-ho to the series format raises the interest of more risky proposals than usual. In this case, the director's ability to mix genres achieves a remarkable result that begins strongly directly in the supernatural terrain and ends up drifting towards a thriller that handles with talent the double realities and the reflection on the limits of science.

Wow... the production is top-tier. but the story is just ok

This is a top-teir production ; the direction is also on point !! it moves from Sci-fi , to horror and then to a thriller and the mixing of genres was blended smoothly like a apple-banana-strawberry shake !! Wishing apple to do more originals like this !! While the ending was a literal bomb ; [spoiler] like really a counter for when the machine will overload ? [/spoiler] and with numerous weak plot lines it is still a recommendable experience ; more so becuase a decade back i floated this thesis of harvesting dead brains neurons for memories was laughed at by peers and academia!!
