With so many movies taking small plots and stretching them to the snapping point, it’s a pleasure to encounter “Wild Tales,” an Argentine film that packs six gripping, entertaining stories into just over two hours. There is more invention, more joy in storytelling, more attitude, more originality and more energy in any 15 minutes of “Wild Tales” than in three-quarters of the movies that get released. The goal is to grab and divert viewers, to take people to places they don’t expect, and to do it quickly and memorably. [...] comes a shift, some unexpected violence, or someone gets angry, or someone sees an opportunity for revenge, and things get crazy. “Wild Tales” has been compared to “The Twilight Zone,” but most “Twilight Zones” turned on either sci-fi or the supernatural. In the second tale, set in a roadside dinner, a meek waitress recognizes the customer as the man who wrecked her life. What follows is a kind of revenge tale, but one that’s really astute about relationships and desire. Though the stories in “Wild Tales” are skillful contraptions, Szifron is careful to ground each tale’s extreme shifts in specific details of character. [...] you may find yourself marveling at the fertility of an imagination that could allow itself to toss so many vivid characters and stories—enough to supply four or five movies — into one generous package.
