8 Horror Movies That Get Better The Deeper You Go

A science-fiction horror movie that will tap dance on your synapses and send your brain into overdrive, Triangle is a film that dresses itself up as a simple lost-at-sea narrative, selling itself on a group that gets caught in a storm whilst yachting and have to jump ship onto an abandoned cruise liner that by chance is passing by. Jess and her friends soon then find themselves victims of a mysterious murderer, and learn that floating atop their capsized yacht is a far preferable fate to whatever is happening aboard the newfound ship.

As it turns out, this isn't your average spooky story, since the ship doesn't subscribe to any normal experience of space and time. Instead, Jess has become party to a time loop, forced into a self-fulfilling prophecy where she kills her friends over and over again in an attempt to break free of its consequences.

On first watch, Triangle is a tangled mess of timelines that is difficult to prise apart. There's exact doubles, jumping forward and backward in the narrative, and heaps of death that doesn't quite make sense until you've seen all the way through. Even then, the precise nature of the loop is still a tricky one to understand in its entirety, requiring multiple rewatches to get to grips with it before you can dive into the theories of its causation.

Triangle is like horror's answer to Primer, the more you dig, the deeper you go, and the more crossed wires you find along the way.
