Metacritic reviews

What Josiah Saw examines religion, trauma, grief, sanity, and familial bonds in a truly unique way. Grashaw elegantly balances the heavy drama, action, and horror moments, crafting an unforgettable journey. Dilts intelligent screenplay is brought to life by a stunning cast giving it their all in every scene.

It is enigmatic and eerie in a manner that crawls under your skin until you feel like you can't escape it. It is proof that films like this, even as they are enormously painful, can reveal the dark truths of being alive in ways other works shy away from. It reflects how life can often have no respite from tragedy, instead burrowing deeper and deeper into it. It succeeds in capturing this state of being, meticulously and ruthlessly ripping away the past until the future comes crashing down.

It has a stubborn, almost literary feel for character that accumulates a baleful momentum by the time the finale hits.

Grashaw’s ability to keep everything moving through that thick air of uncertainty is the film’s best attribute because it does feel like we’ve gone off-track more than once after chapter one (there are three, one for each sibling).

If Grashaw had simply trusted his instincts a little more and allowed Josiah to exist as a simple meditation on one family’s traumas, it would have easily joined the ranks of the great cinematic Southern Gothic horrors.

Sluggish pacing slightly undermines the film’s main assets — the strong performances from Kelli Garner as Mary and a suitably ravaged-looking Nick Stahl as Eli.

Dilts and Grashaw build out What Josiah Saw thoughtfully, letting the dread from one story bleed into the next, until everything is covered in a dark, dark stain.

The family trauma is so clotted-thick, a faster pace and tightened-up editing might have eradicated the slow-motion underwater feel of the whole.
