If you've ever watched Death Note, Sherlock Holmes, Murder at the Orient Express, this series is like mixing an omelette and you don't know when it's going to be fried.
Unclear writing, and contrived conflicts, lack of explanation regarding the mechanism of killing humans by gorillas. too many questions to answer.
and in my opinion, waiting 6 episodes for it, is too long.
For those of you who usually watch dramas like hometown cha cha cha, 18 again, hi bye mama, etc, maybe you can still enjoy this series.
but for me, its a solid 1.5/5
