_The Substance_ aims for impactful moments but ultimately collapses into confusion. The film's graphic depictions become tiresome fairly quickly, and the commentary on society feels so shallow that it eliminates any subtlety the narrative could have possessed. Even with a dedicated performance from the central actor, the story drags, the atmosphere shifts inconsistently between mockery and disorder, and the ending descends into meaningless clamor. It’s an ambitious failure that struggles to establish a clear purpose.
