The film lacks LGBTQ+ characters or any exploration of non-heteronormative identities. The vessel's social ecosystem is depicted through a strictly traditional lens.

The cast is predominantly male, driven by masculine aggression and physical dominance. The narrative reinforces traditional hierarchies of masculine leadership and power.

The story explores 'otherness' through the tension between South Korean fishermen and a North Korean defector. It provides a nuanced look at internal nationalistic divides.

The film excels by deconstructing traditional institutions and moral certainties. It critiques the dehumanizing effects of economic desperation and the breakdown of social order.

There is no significant focus on visible or invisible disabilities. Psychological trauma is treated as a standard thriller element rather than an exploration of disability.
