First of all, Bateman keeps amazing us with his ability to be versatile.
The story is based on Stephan Kings novel. So you go with expecting a supernatural touch to it. The steady pace of the story sprinkled with the gripping moments are highly intense but in a coherent surrounding. So you dont jump off on watching a pivotal scene, but are actually drawn more into it.
The series by far has continued so well, that hopefully the end to it is broadcasted with same thrill.
PS: Brilliant acting.
