Tanglethis has a good post that y’all should go over and mull on a little. My thought is that of course you can have great modern ghost stories. Shoot, I both want to see again and never want to see again The Orphanage. And surely the haunted house will always be with us (at least as long as we’re living in houses).
And I think the analysis of a ghost story being so similar to a detective story is so spot on I wish I’d have thought it. But, and it’s a big but, I think that the resolutions of detective stories are always so satisfying where as the resolutions of ghost stories are almost never. How can they be? You both want the ghost to go away and dread its absence. The explanation is both the resolution and the ruination of the story.
