Crazy Italians are at it again. Purely no holds barred shlock and exploitation. Sometimes uncomfortable (in regards to treatment of certain animals), while other times outrageously jaw-dropping (like the set-pieces involving a cheetah & polar bear). PCP infected water finds its way into a city zoo causing the wild animals to go berserk and break out. Leading to all-out mayhem in this nasty, and gory little eco-shocker. Small scale thrills and spills isolated to the city, but they do pack a punch. Too bad the abrupt ending feels like a cop-out.
