It totally built up to a nice finale, but the only thing is they just had to introduce some mixing of blood magic crap into it, completely killing the sci-fi
In all seriousness, I felt that this episode had potential with its beautiful setting and the enigmatic main actress. But it falls short and it feels like I'm watching the indulgence of a writer and director just wanting to do a murder story for fun but not really tying in any larger themes or clever uses of technology.
