Excellent cast, acting and writing. A crime drama with a stunning setting, Mountain Rangers as the central characters and even a bit of the supernatural thrown in. The latter actually has a sad feel to it.
I loved both Jun Ji Hyun and Joo Ji Hoon in this; her character was strong, capable and assertive, if a little headstrong. It was so enjoyable to see JJH playing a softer character, whose more placid, thoughtful and probing nature, balanced hers.
Oh Jung Se was on fine form as usual, too.
The story twists and turns, moving with the seasons on the mountain, as it is revealed there's a killer on the loose.
The culprit isn't unveiled until the final episodes and so many fit the bill at some point, that guessing was impossible!
I loved the production, location, filming and a soundtrack that suited it so well.
I actually found the ending quite emotional.
What let it down a little were the sudden jumps (from the outset), in the timeline. I didn't get what was going on initially, but once I realised, it was fine; the story is told before and after the events of the deaths, leading up to the capture of the killer.
There were also a couple of characters whose stories and reactions were a bit OTT, but in a drama that had so many good ones, they were bearable.
A couple of episodes were a little slow, but overall this was a great watch.
