Interesting reading that Buzzfeed article and them slamming the idea of celebrity specials. They are of course right.
Talking of the three unaired episodes it is the sort of thing which gets tagged into a repeat run, but actually - and maybe tellingly - they've not really repeated the show that much in comparison to other formats like Gogglebox and 8 out of 10 Cats does Countdown, which seem to air weekly on C4, E4 or More4. When the original revival run was commissioned for 20 episodes it was as if they had a daily repeat run in mind, but they've been quite sparing with the repeats.
It's great that everybody gets sarcasm.
