Upon finding a well-stocked snake pit on the construction site of a high-end apartment complex, its main investor is quick to have the animals killed. But the atrocity has consequences for the tenants. Soon after moving in, they find themselves terrorized by hundreds of hissing, wriggling reptiles. Grindhouse luminary Chi Chang, who rose to fame with Bruce(Lee)sploitation flicks, lands several, often obnoxiously low punches in the down-and-dirty Calamity of Snakes. But he also mesmerizes with an unholy frenzy of images and many WTF moments. (mk)
