A documentary about a literal unsolved mystery should be a slam dunk for weird cinema, but instead it plays it maddeningly straight—the film's restraint in the face of genuine unknowability feels almost cowardly, like it's afraid to lean into the absurdity of the thing itself.
Cusumano constructs a film of genuine formal intelligence, layering acoustic evidence and deep-sea imagery into something that respects both the documentary tradition and the viewer's capacity for contemplative unease—it's a masterclass in how constraint and editing rhythm can make mystery feel earned rather than manufactured.
The decision to let stretches of near-silence sit alongside those whale recordings does the heavy lifting here; lesser hands would've scored this to death, but Cusumano trusts the sound design itself to be the film's architecture, and that single choice transforms a curiosity into something genuinely unsettling.
