On the glaring similaity to their previous work topic, I'm starting to come round to their side. They are known for a certain style of comedy which they introduced and has been copied endlessly. Do commissioners want them to change it? My answer is no, of course they don't. They possibly could write a sitcom in a different vein, but would their fans and the BBC want it? They are famous for their brand of comedy so let them carry on. Moreover, if you've found fame for creating a distinctive product that's had many copies, then I think you might want to drop the odd reminder of who the master is.
If this was their first sitcom, it would be hailed as much as The Office was, possibly more. We just have to get used to seeing the same setups, same 'awkward comedy' thing, same framework again and again. It's lost its impact but I think it's still funny.
BTW I loled at the Derek Noakes clip, whether it's right to or not. It was very funny, and imo, harmless. Is the comedy landscape a better place with Ricky Gervais in it? Very, very much so!
