8.9 was way too much aswell lol so i guess its a fight between super fans and super haters
I found it odd too why most KD have higher rating, usually above 8.0 even though they are just so so and very few good CD have that. I rely on rating to decide which drama to watch. Based on my understanding, that 8.0-8.5 KD score is actually equivalent to 7.5-8.0 CD score.
