An inspired antiwar epic that recently won the Goya Award (Spain’s equivalent to an Oscar) for animated film, Vazquez’s sophomore nightmarish fairy tale culminates with frighteningly revelatory imagery signaling the pattern of destruction that has characterized human history.

A story about drug addiction, corrupt authorities, and environmental collapse sounds grim on paper and plays grim on screen, but Unicorn Wars is more than “grim.” It’s deranged.

As Vázquez keeps adding elements in its last half hour, Unicorn Wars starts to feel like the beginning of a trilogy, or maybe a TV series that got canceled unexpectedly and had to wrap up its storyline in a handful of episodes.

While Unicorn Wars' rhythm can be uneven, the movie is still a brilliant anti-war story elevated by Vazquez’s mesmerizing art direction.

The latest from Spanish writer-director Alberto Vázquez is transgressive and aggressive to a degree that’s hard to fathom: It weaponizes cute cartoon creatures against its audience, and introduces innocence and beauty in order to tear it apart on screen in the most horrific ways possible. The film isn’t an easy watch, but it is a bold and memorable one.

Unicorn Wars is forcefully provocative, trying too hard to push buttons at the cost of more nuanced explorations of masculinity and power. For Vázquez, a pile of cartoon corpses makes enough of a point.

The visually striking, not-at-all-kid-friendly result is all kinds of wrong: Picture pastel-colored anime bears impaled on the horns of sleek black horses, backlit by raging hot-pink infernos. “The Care Bears” this ain’t, though the comparison can hardly be accidental with this ultra-graphic, Saturday morning cartoon-subverting satire for which irreverent Bronies may well be the ideal audience.
