I love it. It did seem very much like they were ending it though. I wouldn't be surprised at all if there were one or two more Xmas specials. But I'd be very surprised if there were any more series.
Er...on the other hand (from the Radio Times, May 2020):
Series star Simon Bird had suggested that the sixth series was "probably the end" of the show - but Popper told RadioTimes.com: "That's news to me! Simon said it feels like it could be the last one. Well, I've no plans to end it now."
Popper continued: "You know, whenever you make a TV series, you always think, 'Well, that's probably our lot' - you never really know. But obviously, the show has now become successful, which is lovely.
"So you'd like to think they'd do it again. I think they [Channel 4] would. But it's also down to me, if I want to do it again. So I always have to think: do I want to do it again or not?"
"I love writing it. So who knows? I haven't got a thought like 'I want to end it'."
