I think The Emperor's new Clothes are finally showing.
You don't have to convince millions of people that your TV idea is funny, you only have to convince the Commissioning Editor for a major TV channel,. and this, Mr Lucas appears to have done.
This is based largely on Little Britain which acted like a firework - burned bright, but briefly, and does not trouble an re--run slots as far as I am aware.
I haven't seen the new show, but based on the aforesaid Little Brittain, and the 'comedy' about an airline, I don't expect it to get a second series. There is really only room for one bafflingly unfunny series to air at a time, and Reeves and Mortimer seem to have that slot.
