I really enjoyed this show. The characters were all super compelling and enjoyable to watch. They had good development of characters and their relationships across the season. The special effects were good although I personally thought that sometimes the monsters looked kinda like clay animation but that didn’t make them bad or less frightening. The monsters were all super unique and terrifying. They made good use of suspense, jump scares and the fight scenes were awesome.
Honestly my only real criticism is just an extremely specific nitpick. I really hated the constant use of the song Warriors by Imagine Dragons. The first time it came on I honestly laughed in what was supposed to be a very dramatic suspenseful moment. The fact that they also used this song in almost every single episode, during the most meaningful moment of many different characters was uhhh not great. It does make me curious to know what koreas relationship with western music is like though cause for it to make it into the show that many times means that a lot of people really liked it lol. It just felt out of place especially since the rest of the soundtrack was mostly normal horror music. Please for the love of god do not use warriors by imagine dragons in the second season.
