Watch New Earth. Get to the point where the Sisters of Plentitude open the hatch and the thing inside begs for mercy. Now then switch to a body getting disembowelled by Leatherface in the prequel to the Texas Chainsaw Massacre.
That's what plenty of American fans are witnessing as they try to enjoy The Complete Second Series. The extras are particularly gruesome.
As flawed discs go, that has to be some kind of record.
Ironically, reliable statistics show that more people die in The Invisible Enemy than The Texas Chainsaw Massacre. And completely unreliable statistics show that more people died in Ressurection of the Daleks than the War in Iraq.
