My appreciation for Event Horizon grows stronger every time I watch it. What I first considered a decent sci-fi flick I now regard as a solid, highly effective horror film. In scientific terms, an event horizon is the point of no return to a black hole... in the film it is also the name of a research vessel which vanished while on an experimental mission generate an artificial black hole. The film begins with the familiar set up from 2001 A Space Odyssey. Years after its disappearance the Event Horizon sends a distress call upon which a salvage crew is sent to investigate. Once they arrive, the crew board the ship to discover evidence of a massacre. The ship suddenly powers-up and sends a shockwave through the crew's own ship, forcing them to board the Event Horizon until their own can be fixed. What they discover is that the Event Horizon actually managed to leave the known universe into another dimension where chaos reigns. Soon they crew begin to experience hallucinations, violent outbursts and complete madness. Its such a great film. It uses familiar conventions with a few cliched elements but it ultimately stands above the ordinary sci-fi horror. In fact I would say its the best sci-fi horror since Alien. Violent, smart and scary.... worthy of repeat viewings!
