Think the presence of these strong casts took the show somewhere unexpected. Lacks the cgi magic (were they broke?) and typical love & romance charm in that of Goblin and Hotel de luna where the characters felt distant and good to look at. Korean Odyssey casts, however, were sitting right in my living with me, they have very strong and likeable individual presence, and that overpowered the re-used hunt the haunt theme of the writers that felt like Master Sun dejavu. Yet while rewatching after a year, I feel the same need to follow through with the whole series, so it's a 10 not for the cgi, ghost hunting, storyline, sweet romance or eventual and must have final plot twist, the 10 is for their star quality.
