I think we really need a film about how bad and antisocial it is to eat burgers and be fat. Maybe the burgers could eat people from the inside out. Then they leap out in a splurge of blood'n'guts and search for their next victim. They lie in wait in their patterned paper wrapper and the weak, despicable fat people can't help themselves.. they reach out.. and it starts all over again. Eventually only the Virtuous Salad Eaters survive and the NHS is saved.

Or

how about rampaging badgers sweeping the country, infecting tiny big-eyed calves with the evil TB virus. And then they could break into people's houses and chew on their throats (with appropriate sound effects and cgi). And then somebody brave could come along and blast them all with a special shotgun-virusblaster. And we all live happily ever after.
