Just finished watching it in one sitting. I like that it only used the Parasyte theme and not adapting the manga plot and storyline. So it makes it look like the Parasyte happening in Korea in the same timeline as Shinichi Izumi.

You know how sometimes you read a manga about end of the world and the heroes are all fighting only in one country and it makes you wonder, "so how does other countries manage the apocalypse?" The Korean parasite is exactly that. It shows how the parasyte takes over Korea. That's why Shinichi can visit her, because they're not making Shinichi Korean ver., but rather making their own heroes. Love it so much. 9/10.

I would love different versions from different countries and have both the Korean and Japanese casts cameo-ing.
