Oink explores man's relationship to pigs, diving headfirst into a beguiling mix of sentimentality and violence - from keeping pigs in your bed to factory farming. The documentary veers wildly from the birth of Dorothy, our saddleback narrator, to zeno-transplantation of organs, from Ralph Steadman cartoons for Animal Farm to wild hogs being machine-gunned from a helicopter. Oink is a mad, bad journey from China to Wiltshire via Brooklyn, which reflects on who we are and how we deal with the world around us.
