i had quite a high expectation for this drama since the reviews and ratings are all good, sadly, it doesn't meet my expectation. the storyline was good, it was very dark and depressing, i feel like there wasn't one happy moment. it wasn't scary but rather disturbing. but, the pace of this drama is too slow for me too too tooo slow. in the first few episodes i thought 'okay lets get through this it will get better', but no it's still super slow. i know it was supposed to build that scary feelings yet it doesn't work for me. there are lots of unnecessary scenes too. the last 2 episodes were okay but it's too late? like out of 16 episodes i only enjoy 2 of them. anyway, the acting were amazinggg.
