Slasher Perfection From Argentina

Argentina takes a fresh crack at the well-trodden path blazed by such horror classics as Texas Chainsaw Massacre and The Hills Have Eyes. What The Waters Left Behind is nasty R-rated horror aimed at dedicated genre fans, a market Hollywood has increasingly abandoned in favor of other demographics. Filmmakers Luciano and Nicolás Onetti have crafted an impressive new entry in the redneck slasher genre that stands toe to toe with the best horror films from the last decade.

A leisurely trip to the flooded town of Epecuén for a documentary filmmaker and his small crew becomes a living nightmare. Located in Argentina, the isolated landscape offers a foreboding presence dripping with menace. Flooded for over thirty years, Vasco has brought his girlfriend and a few friends to film an interview with Carla, one of the few living survivors from Epecuén. Supposedly deserted, the group encounters troubles in the abandoned town that spiral out of control.

What The Waters Left Behind is one of the best horror flicks in recent memory

Known for Francesca and their giallo Abrakadabra, the Onetti brothers more or less make the perfect slasher movie in What The Waters Left Behind. While nothing happening is entirely original, stunning visuals and down-to-earth characters nicely come together. The twists work even if you kind of guess what’s happening. The slickly made film is a bloody good time, delivering exactly what long-starved slasher fans desire. Without pandering to casual moviegoers, the taut script and suspenseful atmosphere hits all the right notes.

Made outside of Hollywood in Argentina, What the Waters Left Behind keenly embraces some of horror’s best-loved tropes without feeling derivative. Elements are plucked from Wrong Turn, Hostel and any number of successful slashers from the past. Yes, the nods to Texas Chainsaw Massacre are blatant and obvious. Having abandoned mid-budget horror films aimed at adults, it’s necessary for outsiders like the Onetti brothers to fill in for Hollywood’s increasingly timid filmmaking.

What The Waters Left Behind is one of the best horror flicks in recent memory with superb acting and electric filmmaking. This is how a slasher should be made with masterful storytelling and a gritty tone.
