"The Endless opens with a quote from cult horror author H.P. Lovecraft, whose dread-filled mythos of ancient alien gods and terrifying occult knowledge is a key influence on Benson and Moorhead's work. But the tone here is more classic low-budget indie drama, restrained and cerebral, than nightmarish horror. Initially, at least... A key future challenge for the duo will be how to bring this fine-grained auteur approach into the commercial mainstream without diluting their strongly original vision." - Stephen Dalton, The Hollywood Reporter
