Love the way certain things connect. Like the dead body in the wall being the tall floating ghost, or the bent neck lady being Nell herself. Also loved the way spirits made themselves present in the past as a whole.
Only complaint is that the ending was a bit sappy. Like, a happy ending is fine, but that was like 15 minutes of a lifetime special.
Still, great show, and I hope the people who made it go on to make more. Maybe adapt a different novel or short story for each series.
