Sintonia grounds itself in the gritty realities of São Paulo’s favelas, focusing on crime, faith, and music without shoehorning ideological messaging. Character development feels natural, with identity reflecting lived experience rather than box-ticking. Forced representation is minimal, and the story prioritizes authenticity over political showmanship.

While the show depicts marginalized communities and complex social issues, it largely avoids attacking traditional values. The role of religion, especially evangelical Christianity, is shown honestly with both its positives and flaws. Masculinity, family, and community are integral rather than pathologized.

Alternative perspectives are present and explored. The show presents characters from different backgrounds, criminals, religious leaders, struggling families, without reducing any one group to a caricature, and there's reasonable debate about morality and life choices.
