I just finished watching the film, and honestly I love the dedication to delivering the narrative from the acting, cameraworks, to the setting. It's such a REALISTIC depiction of how poverty makes people vulnerable, but it also twists its victims' sense of what's moral and/or logical. Matheus and Luka both were victims of poverty, but their ability to rationalize their decisions/actions were radically different from other. The rest of the prisoners could not see the logic of Matheus collaborating with Luca. Throughout the film, Matheus remains pokerfaced.
I would 200% recommend! 👌🏾
