This show is supposed to do for the ghost/ possessed genre what the walking dead has done for the zombie genre. Bring it out of the ridicule into the books of serious TV. I didn't read much else about this show going into it and I am glad for it.
Like many reviewers have said, it's that first scene that completely has you hooked. I was grimacing and enthralled at the same time.
I didn't think too much of the story-line - it seems to echo the usual haunted by a possession in the past trope, but there are some twists that bring it out of the absolutely ordinary. It remains to be seen how well they build on the out-of-the-ordinary elements in the story. Let's remember that TWD also started out regular - a guy waking up in a world inhabited by zombies was very very familiar. It is what they have done with it in the long run that has made it a gem.
This is just the first episode in what appears to be a very promising ghost series. Go Kirkman!!
------------edit post season 1 finale--------- no spoilers!
This is the slow burn that The VVitch tried so hard to accomplish. Things move slowly and deliberately towards tragedies/ triumphs in the storyline. The season ends in a good place, leaving us wanting more.
I wont lie, there are some bits where it seems to drag its feet in petulance, but it does recover. And, boy, when it twists, so do you!!
I would recommend putting in the work to get through the draggy bits for this one.
