Larry David, the creator of Seinfeld and Curb Your Enthusiasm, famously believed his shows should contain "no hugging, no learning". He pioneered a particularly cynical type of comedy, which has inspired countless other shows in which the characters are not particularly great people and often don't get along. While a lot of those shows are brilliant, there's something wonderful about a programme like Brooklyn Nine-Nine in which all of the characters, despite the occasional dispute, fundamentally like each other. The respect and friendship shown between them is often a source of comedy, particularly in the case of the extraordinarily loyal Detective Boyle. But even when there are no jokes involved, the precinct feels like a place where friends hang out and that's a nice world to visit once a week.
