For some time I believed it was overhyped and I was not really into giving it a chance cause from edits I saw I found it a llttle too brutal and a little too disgusting (monsters) but I am happy that in the end I did. Yes there are bloody scenes, the monsters can look ugly and some characters can be a little annoying but it is definitely worth watching. I loved Song Kang and Go MinSi's characters, also their development (not only in this season). There are some funny scenes but also the ones where you will cry. And eventhought there are annoying characters, there are also a lot easy to like .
I like that most dramas do not have next seasons but in this case I am very happy that we got two more.
