When it comes to supersizing, it seems, the burger-and-fries crowd are rank amateurs. The real achievers are the ‘feeders’ – men dedicated to fattening up willingly abject women (‘gainers’) in a setup guaranteed to outrage Drs Atkins and Greer in roughly equal measure. Pegged to this real-life phenomenon, this sick, slick, smug Aussie psycho-thriller comes on like ‘Silence of the Lambs’ but turns out to be more like Russ Meyer carved out of Antony Worrall Thompson. Patrick Thompson plays an IT cop investigating online perversion in its various forms (for starters he busts a German cannibal fellator), alerted to a feeders’ website whose star gainers are going mysteriously AWOL. A little rummaging turns up a Buffalo Bill/Patrick Bateman-style nutter, a prosthetic fat suit and several bin-bags best left alone. Some nice, stylishly lit compositions apart, the film is hobbled by its inane script even before it collapses into gross, sadistic exploitation. You try saying ‘I should have sent you home when I found you crying in the toilets’ with a straight face.
