Completely no surprise here but I love sci-fi horror. Taking cool futuristic concepts and using them to create an atmosphere for horror. I love being fascinated with technology while simultaneously terrified of it. The best example I can think of this, and coincidentally my favorite horror movie?
Event Horizon.
In the not terribly distant future, Humanity creates an FTL drive which is installed aboard a spaceship called the Event Horizon. On her maiden voyage she vanishes. Some 7 years later, a distress call is picked up in a decaying orbit around Neptune from that very ship. A Search and Rescue vessel called the Lewis and Clarke is dispatched, along with the ships creator, to check out the signal and find what went wrong. What they do find is far more than they bargained for as the ship itself seems to be itching to return wherever it originally disappeared to.
Came out in the 1997 with an AMAZING cast. Pre-Matrix Lawrence Fishburne, Sam Neill from Jurassic Park, Pre-Harry Potter/Star Trek/Everything Jason Isaacs, and the stellar Kathleen Quinlan.
There's also a fantastic fan theory that Event Horizon takes place in the Warhammer 40k Universe but far in humanities early history. It's one that I actually buy into. Makes a shocking amount of sense.
