Coming from the acclaimed writer of Signal and Kingdom, expect a non-linear thriller with preternatural elements featuring a solid cast of actors. At its core, this is simply a love story about Mount Jiri and the people who risk their lives to protect it.

Each episode provides glimpses of the various challenges rangers have to face in the course of their duties. There are short, funny anecdotes. And then there are the tragic, haunting ones. Bits of Korea's actual history are woven into the story, with sprinkles of wildlife trivia as well. There is an over-arching mystery following our lead characters that provides us viewers with that sense of urgency to understand what has happened and how to rectify the situation. I also like the very subtle, barely-there, thread of romance.

On the downside, the OST so far has been forgettable and there are some who have been complaining about the CGI.

But for someone who studied at the foot of a mountain reserve and volunteered for ecological activities hosted there, Jirisan is my kind of watch. Mysteries like this usually have a low rewatch value once you've figured out who's who at the end of the series. I think Jirisan will still be a compelling rewatch for me because of its gorgeous backdrop. Right now, it makes me want to go hiking again and join the rangers in their mission.
