Overall, I would say it's good. But there are a lot of scenes that are not essential to the story — shots of Jirisan, sceneries, aerial shots of roads — adding these doesn't automatically make a good cinematography. The overall plot is exciting but there's too much back and forth in the timeline that the story isn't fluid anymore. I also feel like JJH's acting was not utilized to its best potential. We all know JJH and how she can adapt to her character well, and I wish I could've seen that in Jirisan. I guess I'm comparing to how well she performed in Ashin -- not much line but very captivating.
There are some episodes where I feel like I'm just watching because I've already committed myself to it.
