Suffice it to say that the tension ratchets up beautifully, whether through enlightening arguments between the brothers, or through the same skillful editing and cinematography that Benson and Moorhead have exhibited in their past efforts.

The Endless is a masterful cinematic echo chamber with incomprehensible depth. You will feel, laugh and be forced to address emotions shared with all on-screen personalities.

Although The Endless works just fine as a standalone film, looking at it in the wider context of Benson and Moorhead’s work highlights another, more meta theme: the desire to return to an earlier, simpler period in one’s life, and relive those glory days forever.

The Endless is not just about latent power struggles within cults but also within families, and about how both are eclipsed by more ancient, malevolent cosmic forces.

The Endless is a demanding, rewarding picture with moments of unusual terror and awe, offering a science fiction/horror scenario on a literally cosmic scale which boils down to a study of a complicated sibling relationship.
