Haunting of Hill House
I normally never watch horror films or TV shows because they're so unimaginative, but this show on Netflix is great! One little twist is that there are reportedly lots of ghosts popping up in the background of scenes, such as a face in a door panel, or something moving under the corner of a piano, etc., but I've never managed to see one yet.
I have to look them up on the Internet after an episode, but they ARE there! Very watchable.
