I also still very much want someone to take the Gothic governess plot and rewrite it for the start-up age. A recruiter called you and got you a job working for a suspicious new company ... but is there a dead stakeholder in the attic?!?

Hmm, maybe Ex Machina is kind of a Gothic from this perspective! (Movie with a tech bro villain making female robots which I've only seen once but think is very underestimated, much as the tech bro hero is like... I mean I see structurally why you're the protagonist but I care about you by far the least.) There's a kind of wife in the attic figure who escapes and wrecks everything, and there's definitely stuff with doubling, and also race stuff you could probably do a Wide Sargasso Sea on!
