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 US version of The Office, LOL.
Watched 8 episodes and would rather watch paint dry for the rest of my life than watching the rest of the series.
The first series was trash because they pretty much tried a shot for shot copy of the UK version. The second series was basically a reboot and was amazing from there on till about season 6 iirc
