This series does everything right, great character development, great storyline, no plot holes, creepy vibes, sadness and a bit of humor. One off the main things I loved about this series is that the first half off the season dedicated each episode to a certain character it gave me kind off an "IT" feeling and I was thinking if "IT" was a tv show that this would be the perfect style for it.
I don't want to give too much away and I can't trust myself to write a review and ramble on so just one more thing. This is a full round story there's no storylines left to tell with these characters and they all had satisfyingly endings so if there is going to be a season 2 and we all know how Hollywood works they will probably tell the story off one off the ghosts in the hosue.
Anyway I think everyone over the age of 15 should watch this show. It's absolutely brilliant!
