Fantastic acting, production value, cinematography, sound track. It was pretty much a movie production stretched into drama. Ayano Go is amazing here as the 'monster' created from dead people, where a scientist had altered some genetic material and revived. He learns about what it means to live, be a human, and human emotions like love, fear, displacement, friendship. Less sci-fi and more fantasy, and slower paced than it could be, still, its beautiful tone throughout is worth watching every minute. Finely calibrated performances from Ayano and Nikkaido, at a level you don't normally see in TV dramas. Take out the annoying side characters and you have a perfect drama.
