So far I haven't found a weak link in the entire show. Personally I haven't noticed weaknesses in the CG that some critics are stating. The cast is outstanding - Jun Ji Hyun is one of my favorite K actors and she is doing an exceptional job in this drama as she's done in everything she's touched. I enjoyed Joo Ji Hoon in Hyena and he's a perfect match with JJH in this drama. The storyline is growing weekly and is really keeping me hooked in with every episode. Episodes 7 & 8 are the best so far and had me on the edge of my seat throughout. Every week after watching this drama I wanna lace up my hikers, strap on my backpack and head out to the nearest forest for some camping. Not sure I'll be able to find anything as beautiful as Mt Jiri and I hope I don't run into any of the storylines we're experiencing in this drama. Definitely worth a rewatch despite only being at the halfway point.
