I sometimes waiver on what I consider our greatest sitcom but as soon as I settle down with Porridge, there really is only one. The writing, as always from this legendary duo, is immense and the great Ronnie Barker plays what he himself says was his best character. The tragic Richard Beckinsale as the lovable Godber, the vulnerable Mr Barrowclough and, my favourite of the lot, Mr Mackay. When I watch Fulton Mackay's performance closely, I see what a top actor he was. His asides, facial tics, use of the language is all a masterclass of an actor creating his own character. Add to all this the great ensemble of Jock, Warren, Lukewarm and the Governor makes for the greatest sitcom.
