A BBC film on assisted suicide was "biased", critics have said.
Care Not Killing campaigners said Choosing to Die, which shows a British man with motor neurone disease dying, was "pro-assisted suicide propaganda loosely dressed up as a documentary".
And the ex-Bishop of Rochester, Michael Nazir Ali, said it "glorified suicide".
The BBC denied Sir Terry Pratchett's film was biased, saying it was "about one person's experience" and would help viewers make up "their own minds".
The programme showed Peter Smedley, a 71-year-old hotelier, travelling from his home in Guernsey to Switzerland and taking a lethal dose of barbiturates given to him by the Dignitas organisation.
Author Sir Terry, who has Alzheimer's disease, made the film to establish whether he would be able to die at a time and in a way he wanted.
