Scientists at a secret underground complex have found a way to travel to another dimension. Three dimension-travelers are the first to go through the gate - but are soon attacked by something that interrupts the communication with Earth. This horrible something uses the gate to travel back to the underground complex. Most of the staff are evacuated, except four heavily-armed militaries and Dr. Casserly and Dr. Summerfield who just can't stand each other. It turns out that the creature is a alien monster that craves human flesh. Not the best horror film I've seen. Some very nice creature effects and the filmmakers sling some pretty cool gore at us but There's virtually no tension, suspense or atmosphere. It was dull, too, why were all the sets so foggy? Couldn't they afford proper lighting? Or were the sets even complete? It's an OK time waster at best, at worst... 4/10.
