I won't add much to d review as it's explain by others. It's too good, I cried in season 1 & 2. The song - Say my name in season 2 just took my breath away.
My favorite scene in both seasons is the moment when they burn the page containing the missing person details to send them off... After being found...
Hats off to the director, writers, producer, all d actors n d one who came up with this idea/ concept.
