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 (All versions) because the movie “Office Space” exeedingly outshines the humor and plot of any of the TV shows.
As with most “comedy” shows it’s actually a drama disguised with a specific setting and a couple of meme characters to make it look like a comedy.
I’m convinced people only watched that stuff because they were all in on office drama at work/school but didn’t want to admit to that fact.
