First thing the first one: In some places they classified this as a reality show!!! I was enclosed in the COVID and I lost the news about zombies (I love how the Koreans say chombis) working in reality shows in TV programs. Come on whit such a classification.
It is closer to a drama than to a simple TV show but I am not that specialist to judge that. However, a drama is a series whose chapters are interconnected and something is happening to characters to change their focus. Spoiler ahead: The punishment to the coward is no less than the best closing to a drama. So and at the end, this is a drama as far as I can see. So in my particular classification, it is the 340th I have watched. And let me tell you something, I enjoyed all the eight chapters a lot. Maybe I am as fool as a fool with a pen, but I really enjoy them. As I was secluded by force in an unfamiliar environment and Netflix was my only escape, Zombieverse was the best to get it. Watch it. Love it or hate it but enjoy it. You are going to have some very good moments for sure.
