Outnumbered does get tooted as being revived for Christmas, they did it in 2016. But it wasn't as good because the kids had all grown up and a lot of the show's original humour was "out of the mouths of babes" as it were (and being partly improvised around that). That doesn't quite work when the youngest child is 16 years old but I think if it was revived it'll be one of those "couldn't be lucky a second time round" things.
Exactly, and they did a Men Behaving Badly sketch for Stand Up For Cancer in 2014 (with Dorothy or Deborah; they're now inflatable dolls with their faces on them) and it wasn't that good.
The other thing is, we shouldn't just keep bringing things back. It's a very base desire to see what the "old gang" are up to, but when you do, you realise that you wish you hadn't. Very, very few exceptions to this rule. The Fast Show only just about worked on Gold, and even then there was no Caroline Aherne. Gavin and Stacey did bring in lots of viewers, but again, it last aired a decade ago.
The point is that the BBC should be trying new shows and then doing a special of those, but when they do, they don't put them on the big day. The most obvious example was Ghosts, which has had two great series, but they aired the Christmas special on the 23rd December when it could easily aired on Christmas Day, or at least Christmas Eve. I just don't understand what executives are running the place. I can only assume that they are hipster types who really don't "get" comedy, but think that a demographic must be catered for and look to please that instead.
