Hello, new here! I wrote my first short story before Christmas that I enjoyed so much I thought it might make an interesting screenplay, but decided I'd first take the basic idea and try to expand it into a novel, which is why I've now signed up to this creative writing forum today The short story itself was a horror, that never actually revealed who or what the antagonist was - but for a few subtle hints that suggested it might be a supernatural occurrence - and had no resolution to it other than the protagonists survived, unharmed, suffering nothing more than a rather chilling night. This has essentially formed the basis of the first half of my novel, with the events of that night climaxing in a different way but still unresolved, which then leads into the second half of the novel, set a few years later. The question I have, is that I don't think I want to go down the route of an explicit ending explaining exactly what happened and why. I would like to maintain the question of whether it was psychological or supernatural, and end it in a way that is ambiguous as to who or what was ultimately responsible for the events in the book, similar to how some films end in a way that leaves you asking for your interpretation of the events, Inception, Shutter Island and Blade Runner come to mind. Is this generally accept in the literature world or do most people prefer signposted endings that wrap up everything nicely? I admit my knowledge of literature is rather lacking, I haven't read much more than a few crime novels by Mark Billingham, and a handful of (auto)biographies = hence my examples from the world of film rather than books.* My aim is to finish this novel and then develop it into a screenplay, with the first film ending at the conclusion of the first half of the novel, which I personally think is an interesting climax in itself. * I'm aware that Shutter Island and Bladerunner began as a novel and short story respectively, I've just not read them so don't know if the ambiguous nature of their film versions were taken from the original source.
