Tin & Tina is a chilling horror film that delves into the disturbing impact of religious indoctrination. Set in Spain during the 1980s, it follows Lola and Adolfo, a couple struggling with grief after losing their unborn children. Their decision to adopt Tin and Tina, two eerily well-behaved orphans, quickly turns into a nightmare when the children’s extreme interpretation of biblical teachings leads to unsettling and violent consequences.

The film draws comparisons to classic horror titles featuring sinister children (The Omen, Orphan, Children of the Corn), but unlike typical “evil child” movies, Tin and Tina’s actions stem from genuine belief rather than malice. This distinction creates an unsettling moral dilemma for the audience. The movie’s psychological horror elements are heightened by its oppressive atmosphere, eerie cinematography, and an ambiguous ending that leaves viewers questioning the nature of faith and fanaticism​.

Despite its strengths, Tin & Tina has been criticized for being too long, with an overly drawn-out narrative that diminishes its impact. The film also includes controversial moments, such as an implied act of animal harm, which may unsettle some viewers. However, for fans of slow-burning horror with a deep thematic core, it remains a compelling watch​.

Overall, Tin & Tina is an unnerving exploration of religious extremism wrapped in a psychological horror narrative. While not a traditional jump-scare horror film, its eerie atmosphere and disturbing themes make it a unique addition to the genre.
