Director Bong Joon Ho's uneven movie is about a girl, her giant, adorable pet pig and an evil corporation that wants to separate them — and also to separate our porcine heroine into bacon strips. There's an inconsistent tone, with horrific moments spliced with satire and detours into vaudeville and a few moments when it's kidnapped into a heist movie. [...] Bong must be congratulated for forcing us to see what's for dinner, even if his message is as heavy-handed as a public service announcement for veganism. The film centers on the fate of Okja, who was created by the malevolent Mirando Corp.
