This is an amazing adaptation to the Japanese version. It follows a really similar story line for those who has read or seen the Parasyte Movies. It gives Sweet Home vibes as well.
Besides the action of this show the creators have been able to create a suspenseful plot and an incredible layer of depth and insight to the human condition. Using these beings as a way to unravel how human's think from an external perspective. Sooin's parasyte is also able to use her external insight in order to show Soo-in the things that she herself was unwilling or unable to see and it helped to develop more layers to her character without boring the audience.
I really enjoyed the ending of the show, it is leading me to hope that there are more seasons to come.
