So far I'm getting the vibe of Gu Family Book and Along with the Gods with a twist of modern setting from the drama. Which is quite an interesting combination that sets the drama apart from a lot of past dramas involving gumiho or nine-tailed foxes.

Lee Dongwook as Lee Yeon gave us quite an interesting character that occassionally reminds us to Goblin's Grimreaper, which can be quite endearing to watch. Kim Bum as Lee Rang at first glance so far gave an impression that he'd be an interesting villain.

The drama so far do still give homage to many of Korean mythological creatures besides gumiho while also giving us a hint of mystery. It'll be interesting to see what the plot of Tale of the Nine-tailed will show us next.
