For me if I had to pick a good contender it would be the UK version of The Office.
I know many tend to debate how Ricky Gervais really fell off and how he repugnantly acts like a whiny centrist edgelord but me personally IMO I actually don’t think he was ever funny not even a little.
His big break through television was just so painful to sit through it’s so charismatically boring the characters are completely generic at best (notably Tim) or straight up insufferably unlikable at worst (especially the protagonist David FUCKING Brent) and most importantly the humour is just embarrassing.
Always seemed like The Thick Of It but without the nuisance tongue in cheek and charming satire.
It was special because “everyone” watched it. The meh or bad parts were whatever, while the exciting or good parts were something you could talk with all your friends about at school. This made the good parts uniquely good.
So unless you happened to both be alive and watch it when it ran, it just won’t be amazing.
Alternately, you were “the kind of person who didn’t watch Friends”, which still made it a cultural touchstone.
