"The Signal" is more horror film than sci-fi. It's about three people trapped in a threatening environment they do not understand. It is also about reality, and how our concept of it can easily be shaken by unexpected circumstances that are inconsistent with our past experiences and perceptions. In the early portion of the film there is a brief reference to Philip Dick, the master of reality tales, and to his book "Do Androids Dream of Electric Sheep," which became the basis for the film "Blade Runner." Later references capture some of the mystique of "The Matrix" and also an often overlooked film from 1997, "The Cube."
Comments posted here about "The Signal" seem to be sharply divided: viewers seem to either hate it or love it. The displeasure is easy to understand. Those who expected a sci-fi story with a lot of techno-gadgets and special effects are likely to be disappointed. The same applies to those who are uncomfortable with the concept of victimization, a common basis for horror films and a key element in "The Signal." But those who like to read Philip Dick or who enjoyed "The Cube" will find much to admire in this film, a low budget effort with a smart script.
