This solidly engaging, supersized 2000 Mexican drama by Alejandro Gonzalez Iñarritu provides a look at the dog days of love through three separate stories linked by a calamitous car crash and some recurring canine characters. The feral rage and ugly aggressiveness of dogfighting (all simulated) characterize the first story, about a battered teenage wife’s on-again, off-again attraction to her gentle, utterly infatuated brother-in-law. Obsessive love for a cuddly mutt proves highly symbolic in the second story, which chronicles a middle-aged married man’s new start in life with a model half his age. In the third story, compassion for a dying dog becomes a turning point for an aging contract killer. The second story, with its soap opera characters and some surreal silliness about a dog trapped under a floor, is the weakest. The first and third—with their strong casting and ability to convey the flavor of Mexican lifestyles, high and low—carry the film. In Spanish with subtitles.
