from my understanding of the pilot:
the original owner of the house was the scared medical doctor who burned and murdered his family. then we have the gay couple who bought the house and ended up dead with murder suicide. and then we have the twins who I believe were the third victims of the house directly.
Now the woman who sold the house to the family is one of the spirts as is the maid and the fucked up kid who is hanging out with the daughter. the neighbors are really fucked up especially the little girl <(who I think is a rip off from the shining.) we all so have the spirt in the black sex gear who was fucking the wife.
now didi I miss any thing and whats not to get. this is going to be simmilar to the shining but more complex.
