A simple mystery where all cameras could have been placed on a letter box to check who is placing those letters was simply twisted and turned unnecessarily. It was like a curious prank teaser video where you keep watching it till the end and come to know there is nothing else more to learn. I liked only till first three episodes. Good acting, exotic locations, good editing is the only reason why I could watch it till the end. Not revealing became the habit of director which went too far. It was turning out to be good watch which lacked logic big time and sadly made me also just the undiscovered watcher of the series.
