Project Silence is, in essence, a Korean Cujo, with a few extra's.
First off, there's the attack dogs, military experiments, who have gone awry. Its no a bad start, helped by the addition of disaster film tropes such as really bad car pile up's, crashing helicopters, negative weather conditions and more.
Taken as whole, the result is a decent horror/disaster mash up. The characterisations even have some depth, which further adds to the appeal.
In summary, whilst not outstanding Project Silence overcomes the obvious downside, associated with what is, a limited concept by cleverly bringing together enough varied elements, to make this film inherently watchable. Certainly worth a look.
