I listened to the radio version of this on Radio 4 extra with great enjoyment. The TV version compares very unfavourably indeed.

On the radio Mark Heap and Peter Serafinowicz shine as Aziraphale and Crowley. Their delivery is amusing, engaging and convincing. Again. On the radio version Clive Russell is simply superb as Shadwell - a joy to listen to.

Watching the same material brought to the screen is like a kick in the teeth. Michael Sheen's Aziraphale is anodyne. I have no idea what David Tennant is doing with Crowley. He seems to be mixing up a collection of poor impersonations in ever varying quantities (Mark Bolan, Adam Ant, Johnny Depp, Bill Nighy, Joseph Gilgun...........) giving us a vacillating abomination.

Michael McKean has a "Mc" in his name and so presumably was an obvious casting choice for the Scot Shadwell. But Michael McKean is from New York and his Scottish accent is so cringingly poor it would leave Dick Van Dyke feeling vindicated. Take a few moments to listen to Clive Russell in the radio version for the real McCoy.

Be kind to your brain - avoid the TV version and catch the radio series if and while you still can.

Season Two is even worse. It is like season one badly lobotomised as the intelligence of Pratchett is not there. Great book, great radio show with Heap and Serafinowicz but the TV show is not in the same league.
