“Spectacular and incoherent.” Read on for the verdict on last night’s TV.

Life, BBC1

“Without [Attenborough’s] benign narration, Life would essentially be about things killing things.”
Nancy Banks-Smith, The Guardian

“I cannot have been the only viewer so conditioned by modern-day television smart-aleckry that initially, Sir David Attenborough’s commentary notwithstanding, I thought the dolphins were manufacturing the BBC2 logo.”
Brian Viner, The Independent

“As spectacular and incoherent as a coral reef.”
Andrew Billen, The Times

“The camera and the computer have taken over from the knowledge and the charisma of the presenter.”
Matt Baylis, Daily Express

The Enemy Within, Channel 4

“I like Bullman’s novel approach to documentaries, I just didn’t think this one quite worked.”
Andrew Billen, The Times

“Inventive comparison between 19th-century anarchists and those modern-day Muslims with axes to grind and bombs to plant.”
Brian Viner, The Independent
