"Silvestrini, in only his second feature, does an excellent job of sustaining the tension in a situation where it would be easy for the audience, as well as the protagonist, to despair. Sandra's inventiveness keeps things interesting and mans we escape the familiar frustration of watching idiots flounder around onscreen. He also coaxes a perfect performance from young Hodges that makes the child more than just a motivating factor for Sandra - a person we can care about in his own right. The occasional sentimental note can be excused because it does feel earned, and when it's time for action, the film really delivers.
It's said that onscreen monsters are often at their most imposing when doing very little. Monolith can give most car chase spectaculars a run for their money."✮✮✮✮ - Eye For Film
When you think Sandra has tried everything and she is beat, she finds one more drastic moment of inspiration - the ultimate test of the Monolith’s safety features. A fitting and real end to a surprisingly action packed film." - Britflicks
"One of the film’s biggest strengths however is that Silvestrini manages – despite the flimsy plot – to keep the viewer riveted for its entire duration. One of the secrets of this I would hazard a guess is the originality of the car at the centre of the story. As vehicles in real-life become increasingly sophisticated, providing the last word in comfort and protection for their passengers from the world without, the most terrifying aspect of Monolith is that it will most likely be a case not of if, but when, we see such things in reality. (...) the viewer feels anything less than impressed with Silvestrini and his team’s ability to make you believe in what is taking place." ✮✮✮✮ - Scream Horror Magazine
