I was initially impressed by the production quality, screenplay and writing which dared to pull off twists which stir the emotions and keep you wondering what happens next. That and it was a fresh take on Japanese dramas which didn't have the usual anime-derived dramatisations.
However holes start to appear when it appears certain characters are so omnipresent but yet oblivious where the plot armour resides.
Then the season finale slips on its own banana peel in the last episode. There were so many unrealistic interactions as some characters and sequences suddenly suffer from the usual prolonging, dramatisations and silliness to force the series to end on a certain note and pave the way for a money grabbing 2nd season.
Rest assured it did not get my thumbs up from the choices given after the show ended.
