Denounced by animal-rights activists for its depiction of brutal dog fights, "Amores Perros" is a bizarre mix of parable and social commentary. Neophyte director Alejandro Gonzalez Inarritu chooses an ambitious project to mark his debut, a meditation on love's difficulties and fate's cruel machinations. He entwines three separate love stories involving three very different classes of people. Not all of these stories are equally interesting, and one of them would have been best on its own. With a car accident as his narrative anchor, he binds the fates of these previously unrelated lives, but also uses the setup as an excuse to employ stylistic gymnastics. Proving that he can juggle a variety of timeframes, perspectives and moods, Inarritu hints at a vibrant pastiche of human relations but in the end succumbs to the dangers of such a fractured narrative practice: too much bravado, not enough soul. Starring Emilio Echevarria, Gael Garcia Bernal and Goya Toledo. Directed and produced by Alejandro Gonzalez Inarritu. Written by Guillermo Arriaga. A Lions Gate release. Drama. Spanish-language; subtitled. Rated R for violence/gore, language and sexuality.. Running time: 153 min.
