Asian Horror has a unique naturality to it and it is one of those. It isn't the best but I would prefer it over Cursed and The Order anyday.The asian horror genre could be explored beyond " the grudge"and has a lot to offer.
It can be made better from where this series came from if the feedbacks take into consideration.
Its been a series of teenage cringe fest lately in the shows released by Netflix but again you don't really have an option in quarantine.(Cursed,The Order and Warrior Nun). I would totally be up for a season 2 with a well knit story, improvisation and a lot of quality horror.
