It's funny and at the same time bittersweet. This show is like creators nod to viewers' inner turmoil after Tale of Nine-Tailed. This gives the viewers further look into the relationship between the two brothers, which is funny, silly, at times absurd and heart wrenching.

While we don't see the big character arc of Lee Yeon, more like a redemption arc in regards to his brother - what he didn't do while his brother was still alive, and at the same time Yeon becomes the cataclysm for Lee Rangs characters' development, and boy do we get a lot of that. Kim Bum did an excellent job portraying Lee Rang.

What I liked the most is that even the silliest and funniest moment (there was quite a bit of that, where I was practically rolling and had to pause just to laugh it out) the underlying message was that the relationships that those characters have, whatever that may be, allows these kinds of situations: reaction, remark, response, banter, you name it. There were times when I was starting to think "ok, they are going a little bit overboard with the jokes and funny moments" and, interestingly enough, the show became a tiny bit more serious. It was still funny, but it's like they found their footing, the balance between seriousness and slyness.

In terms of romance, it's really in the back. As the focus of the show was more sibling relationship and friendship, however, there were some bits. On the other hand, some of those relationships did leave some plot holes connecting the first show with this one. I did not manage to fully fill them, but I do have some theories - 80 years is a long time, a lot could have happened, there are definitely some untold stories.

I am one of those viewers for whom soundtrack can either make or fail the production. The soundtrack was on point. No other words needed.

Special effects were decent, nothing to complain about.

Overall it was very enjoyable and easy watch, i gave it 9.5 (0.5 reduction for the plot holes), Rewatch value also 9.5, I will definitely rewatch it again, but i am afraid it's not that kind of show which you can rewatch over and over again and each time find new points and details that you have not noticed before. Maybe i will prove myself wrong :)

For those who read this before watching - I really hope you will enjoy it;
