A lot of people will tell you that this is not as 'scary', not as 'good' as the The Haunting of Hill House but it's a different story and it's a brilliant story. I can only vouch for what I felt while watching the show.
The director takes the approach of slowly unveiling a puzzle board to the audience and you have to put the look at the complete picture but by bit.
Without giving out much, I can say this much - You have to recognize if this is a ghost story or a love story, or a story of humans forever seeking remembrance above all.
