I am a parasyte anime viewer and I finished the Korean drama adaption today.
I like how it is showing what happens in Korea when Parasytes were created and scattered all over the world instead of remaking the existing story with Korean actors. Which makes it worth watching for current fans and intrigues the the new viewers to explore the original story.
The story telling is great. It keeps the core question from the origin series- the purpose of our existence. It also shows emotions development, as much as they could in 6 episodes.
Loved the ending theme angle where Shinichi showed up and sticked out Migi to greet the Grey team's leader.
Thank you, I enjoyed it.
P.S: When Heidi splits her head, she is pretty as Tomie.
