Once you get past the first few episodes you start to realize that there's something suspicious going on in the mountain. It really keeps getting interesting though out the show. The cast was awesome. I don't think there's a bad character. there are some heartbreaking moments in the show. if you're not one of those types of dramas. Then I would not watch this one. I have watched a lot of great Korean dramas. I'd have to say that this is a top 15 drama for me. it's really good and worth checking out.
