Story: This is Twilight knock-off - supernatural beings, a fox and a snake (but both looking like hot human men of course) fight over a human woman below their league - but without a proper love triangle and with much older ML and FL which is the main problem. You can't have characters in their 30s behave like teenagers and expect that to work. The romance in this is beyond awful and drags the whole thing down. ML and FL have zero chemsitry, are very unlikable and their romantic montages are diabetes inducing and cringe. They worked OK when they weren't romantically linked (yet) but were more of Mulder and Scully in the earlier episodes. But the show rushed to make them a couple without a proper foundation and then proceeded to make their romantic scenes more and more inane and senseless. Cases in point: SPOILERS The couple takes a romantic getaway while ML's brother is lying in coma on the verge of death. They also take numerous dates in restaurants and amusement parks during a deadly outbreak. SPOILERS END

Not all is this bad which is why the show is so frustrating. The bromance between 2 fox brother is really compelling and should have been the main story, without romance preferably, or with romance as a side not focus. This is also the reason why first 9 episodes (some lagging in episodes 5 and 6 notwithstanding) are stronger than episodes 10-16. They are more focused on brothers and Ep 9, which is the best in show, brings their relationship to a satisfying closure. If only the show ended there.

Acting: ML and FL are awful. Maybe it's because they play characters who should be much younger than their age. The constant and nonsense vows to save one another as if no one else matters (his brother and friends, her parents and friends, people who were dying because of them) are tiresome but at least understandable for teen characters. Not so for 30somethings, one of them being a career woman who should know better.

I'm sorry LDW fans but he is just playing himself, always acting self-conscious "ain't I the hottest thing?" with repetitive smugness, pouting and one brow raising. I have a feeling that this was meant to be his Goblin where he was ML not SML like in Goblin. And indeed, the show panders to him so much, more than dramas usually pander to their MLs, that I'm positive that this is a vanity project. Not only that every character who isn't his got shafted in order to make his character always look cool, but SPOILERS the last episode is literally one long LDW praising reel. It even ruins secondary characters' wedding for they and guests are asked to praise LDW('s character) which takes attention away from them. SPOILERS END

Jo Bo Ah is both miscast and awful in this. She just doesn't cut it as someone who would have a Mountain God spend 600 years pining for her and who would get a teenage or barely out of his teens Snake God-posing-as-an-intern horny for her (especially when truly beautiful fox Yu Ri is right there). Also, there's no real difference between Ji Ah and Jia Ah Imugi. They both bulge their eyes a lot as if crazy, but I guess Jiah cries a lot while Jiah Imugi laughs a lot so that's the distinction.

The standout and the reason to watch this is Kim Bum. He is just terrific, giving a layered, believable performance that's much stronger than many awarded ones from more popular shows. Skip the romance and watch for Kim Bum is my advice.

The supporting cast runs circles around ML and FL despite having nothing to work with for all characters were massively underwritten. I honestly can't say a bad thing about about any of them for they did the job and made characters out of nothing and had a strong rapport. Also, Kim Yong-ji is so beautiful and likable, she would have been FL with Kim Bum as ML. Now that would sizzle.

OST: Amazing. Together with Kim Bum and supporting cast, it's the show's strongest link.

Rewatch Value: Low. Rewatch for Kim Bum. He gave a tremendous performance that deserves to be seen. Skip ML/FL drivel. It's really that bad and there are good romances in other dramas so why waste time on a terrible one?

Overall: Squandered potential, a drama that starts as X Files but ends up as Twilight and even butchers that premise. There is no reason to make the (much younger) villain horny for the heroine if there is no payoff. Though the noona romance tease is more interesting than vanilla crap with ML and FL and at least the young villain conveys that he wants to jump in the sack with FL. Something that is entirely absent from ML and FL interplay. They are too busy making vows to save each other and crying 5 times per episode than actually looking like they want each other. I know that dramas are super chaste but many actors know how to convey real desire unlike these two. They are all platitudes and no passion.

Also, too many characters that don't add up to anything. As enjoyable as they may be in a vacuum, about 50% of them had no consequence and no real role in the main conflict between the heroes (ML and FL) and the villain. And speaking of the latter, you cannot have an effective villain if you don't let him move the needle. He has to do something that raises stakes for the heroes and creates a serious setback for them. Instead, he was given nothing because it was mandated that ML had to be the smartest man in the room every time. Imagine Avengers: Endgame without Thanos winning in Infinity War. There would be no Endgame. You have to let the villain win, and win big, to have a big payoff. This drama has no payoff cause there were never stakes and there were never stakes cause ML was too cool, smart, always prevailed in every episode and thus killed any suspense and stakes that could have arisen from villain's actions. In short, drama without drama.
