That was a superb thrilling experience, the biggest thing was it only has 12 Episodes. From the first frame to the 12th Epi end the whole story moving with many complicated situation and science which make this drama a good sci-fi thriller. I don't want to talk about the science behind this. Also not so sure about the logics of the things they are dealing. So all am very glad about the way the story moving on to you, it has so many emotional moments and also very interesting plot changes.

I have to mention the background score and Track's that playing every time throughout the whole journey of this drama. Just brilliant, that itself made this into a different experience for sure, so OST played a big part here and the way they managed the story in a very intriguing in some point and that kept the viewers curiosity at its peak was also superb.

Also that one Episode the plot change was very sudden but they brought a new track to the story which was completely sensible i don't exactly remember that Episode number but so many things happened in that single Episode which was very wondering. From there on the whole mood was totally different and even more thrilling..

Just 12 Episodes is perfect, already knew there will be a wide ending with something left behind for a second season, climax scenes were very promising...

This drama is a complete treat for thriller supernatural drama lovers. A Must watch one
