The film integrates Ronnie Kray’s queer identity into his psychological instability rather than using it as a punchline. This nuanced approach explores the friction between his private life and the hyper-masculine criminal underworld.

Female characters like Frances and Violet primarily serve as emotional anchors or collateral damage. They lack the agency to drive the plot, remaining reactive figures within a male-dominated landscape.

The cast is largely a homogeneous white British group, reflecting the 1960s East End setting. The narrative focuses strictly on the localized, ethnic-specific dynamics of the London gangland scene.

The story employs moral relativism, presenting the twins' charisma alongside their brutality. It depicts a breakdown of traditional authority, framing the brothers as figures operating outside established social institutions.

Ronnie Kray’s psychological volatility is a central, defining element of his character arc. However, the portrayal occasionally leans into the trope of using mental health to drive thriller elements.
