I saw all the 7 episodes in 1 day, so I'll say it's definitely gripping and worth a binge. It's a masterclass detective story where you see how emotional experiences of many incidents web a complicated psychosis of a character.
Primary and secondary characters in the show are very realistic or humanistic in the way they react to different situations, may it be the positive characters or the negative ones.
Good writing, good performance and very well made.
