I love horror and I think the more extreme the better but your concept is retarded.
>6 trans women go to a haunted house
Why 6, why haunted? I get trans because you want to make a propaganda piece but the rest needs to be justified in some way. 6 is a lot of characters especially if they "slowly" kill themselves. Haunted is something that needs thought too. Ghosts are always metaphors, what are yours metaphors for?
>they slowly kill themselves in more and more gruesome ways
Why is it always suicide? Do the ghosts (?) force them to kill themselves, why are the ghosts doing that? Is the house haunted by the ghosts of trans people or what?
>last trannny detransitions and escapes the house
How? The detransition in the house? Is there a medical office and a doctor in the house, do they wait for the HRT to run out? This seems unfocused.
If you want to make an anti-trans movie you should probably make it metaphorical instead of so upfront. I know most of your intended audience won't get it, but it'll be a better movie. Look at like, Sleepaway Camp where the killer was a trans girl who went crazy from being forced into being trans. Much much better concept and a superior work of propaganda (especially since trans people inexplicably like that film).
