10 Painfully Underrated Sci-Fi Horror Movies

10. Cube (1997)

Cube is a low-budget gem that received fairly average reviews and a cult following, but the sheer commitment to its secrecy is what makes it such a worthwhile viewing experience.

5 strangers wake up in the titular cube, a maze of seemingly endless identical square rooms. Unfortunately, the rooms are also littered with a wide assortment of booby traps that are rigged to deal out death in a viscous variety of gruesome ways.

All the characters want to do is survive the weird predicament they find themselves in, but they all have personalities seemingly designed to cause disruption as they clash constantly with cabin fever quickly setting in.

The whole film is one big mystery that unfolds at a great pace as you learn more about the cube itself and its newest residents. It's also a smart film to test your wits against, as the characters intelligently deduce the numerous tests despite the mass of confusion surrounding them.

The film really benefits from holding back explanations in its unique plot and a muted, claustrophobic atmosphere keeps the tension constantly high as you never feel truly safe.

This is a movie well worth your time, where the horror comes from the fear of the unknown. That and the crazy booby traps of course.
