What are the main features of the 'off by mortis ghost story'?

I'm not sure specifically which 'off by mortis ghost story' you are referring to. There could be many ghost stories with various names. Maybe it's a very local or newly created one.

The Jinmenken ghost story may feature elements like a sense of foreboding that is unique to the Jinmenken location. There could be specific cultural or historical references that add to the spookiness. For instance, if there were old traditions or historical events in Jinmenken that had a dark side, these could be incorporated into the story. Also, the way the ghosts are described, whether they are vengeful spirits or lost souls, would be an important feature. And perhaps there are certain times or conditions in the story, like a full moon or a particular anniversary, when the paranormal activities are more likely to occur.

One main feature is the presence of Civil War - related ghosts. Since Vicksburg was a significant battleground, many of the ghosts are soldiers. Another is the haunted locations like old forts and hospitals.

It has great special effects and a compelling story. The acting is also quite good.

I don't know for sure, but it might have a spooky setting in an old mill.

One main feature is the presence of ghosts with distinct personalities. They can be kind - hearted, like some ghosts who help humans, or malevolent, seeking revenge. Another feature is the cultural backdrop. It's deeply rooted in Chinese traditional beliefs about the afterlife, yin and yang, and karma.

I don't know the exact details, but it might have a spooky setting like a dark forest or an abandoned building.

The main features could be multiple. First, the VR experience would likely provide a sense of presence, making the users feel like they are part of the story with the sisters. Second, the story itself might have a unique plot structure, perhaps with twists and turns related to the ghost. Third, the visual and audio elements would work together to create a truly immersive and spooky atmosphere. The lighting effects in the VR could be used to enhance the sense of mystery and fear, and the voices of the sisters and the ghost would be carefully designed to add to the overall experience.

As I don't know the story well, it's difficult to say for sure. But perhaps the main feature could be the character of Cornelius Larue himself. He might be the central figure around which all the spooky events revolve.

If this is a ghost story related to Melvyn Douglas, it might have a character played by him who is either a skeptic or a believer in the supernatural from the start. The main features could also include some sort of paranormal activity like objects moving on their own or cold spots. These are common in ghost stories and could very well be part of this particular story too. Without more information, we can only guess.
