The first few episodes of Season 1 introduce you nicely to the characters and their backstory with a nice blend of action and exposition. The main female lead has a positive quirky personality juxtaposed by the main male leads very serious and blank no nonsense one. Their "love" story has some humorous moments as well as some poignant ones.
However, those positives are mixed into a show that, almost as soon as the introductions are complete. Dives headfirst into simply being the main characters plus side character(s) dialoguing endlessly about how to solve or understand a particular mystery.
The first instance of this "Wall of Text" approach is at the lake with the water god. This concept is somewhat interesting, yet despite it's first instance still feels like it's dragging it's feet. It's main benefit over the rest of the season being that it is feels better paced than the next main plot of the Steel Lady. This is where you run face first into entire episodes of nothing but people talking together in a room about hypotheticals and uninteresting solutions. This continues on for several episodes in a row with barely anything else in-between and for only a brief time. At that point it becomes very difficult to continue to care about the story as it becomes repetitive and you'll care less due to the intentionally misleading brainstorms of the main female lead.
I suppose if supernatural mystery is your preferred genre then this show might be right up your alley. I found it far far too dull and exhausting to finish the second seasons. However, I will say Episodes 2,3, and 4 of season 2 where by far my favorite of the entire series.
