There's something about sci-fi horror that hits all the buttons for me. Derelict spaceships the size of cities, creatures engineered by science or nature to be perfect predators and the claustrophobia of space all manage to get me excited every time. The Alien franchise made me fall in love with this sub-genre, along with gems like Dark City and Event Horizon.
One of my lesser-known favorites is Pandorum. Released in 2009, it's a claustrophobic trip into space where a mechanic wakes up on a colony ship to see that things have gone very wrong. There's a derelict spaceship, terrible things hunting through the hallways and a mystery unfolding in the bowels of the ship. It gives off big Dead Space vibes, and it's an underrated classic.
