Helix

Helix drops a CDC team into a research station buried somewhere in the Arctic, sent to work out what has gone wrong before whatever it is gets any further. The ice outside isn't the only thing sealing them in.

This is the fear of being trapped with something you can't see spreading between the walls. Less jump scare, more the slow creep of realising nobody left in that building can be fully trusted, least of all the people meant to be keeping everyone safe.

Watch it on a night when you want dread rather than gore, the sort of evening where the heating's on but you still feel cold by the end. It's for anyone who likes their horror clinical and controlled, unravelling slowly rather than jumping out at you. It rewards patience over a quick scare.

Ronald D. Moore created it, and it ran for two seasons on Syfy, twenty six episodes altogether, which is enough time for that isolation to properly settle in.
