Oof. The review was... silly (seemed to be taking lines as some sort of author insert, or the writer's views, put in the mouth of a character shown to not really being liked by the town anyway), but lashing out at reviewers isn't the best move.
I liked it enough, feels like it's setting the characters up and that rest of the run will be solid/better and hopefully funnier. Manford even tweeted about it setting up an ensemble cast. And I felt it introduced them well, so I hope it gets better. I didn't actually laugh, though did find a few lines amusing. Particularly the workmate asking if it's "disrespectful to change the toilet seat" after the old lady died there. And "I've just been given the Phil Collins back catalogue" "My condolences".
Definitely has that comedy-drama (even, as others have said, a bit soap-like) lean a bunch of other modern comedy has. I'd still call it a sitcom of course.
As Rood Eye put it above, the foundations have been laid and it has tons of potential. A good writer and a talented cast here, so I predict a quality series by the end. I hope!
