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.


The Office
Napoleon Dynamite
Grease
Reservoir Dogs
Big Bang Theory (or any popular laugh-track sitcom post 2000)(Nevermind, you said highly extolled, not just popular)
Chicago, Rent, and Cats
Harry Potter (even before JKR went full terf, probably just a generational thing, honestly)
Taylor Swift (again, nothing personal, just not my jam)
Sideways, Marriage Story, Whiplash (intense interpersonal drama, particularly dealing with infidelity or power disparity)
