I love Stranger. It is the best show of its kind - just the right amount of mystery mixed with intelligent power struggles between the characters. The show grabs your attention from minute one and never lets up the suspense. Plus, the chemistry between the two leading actors is simply amazing, their acting so natural that you will forget it's all a tv show.
Lastly, the logic of the actions taken by the characters is airtight. Everyone does things with a reasonable motivation, which may sound basic, but is very rarely actually achieved by any other show.
This is a show you will watch with your full attention without fast forwarding. I guarantee it, just watch and find out.
