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.
This is a style that I first noticed with Archer, and it is very hard to do well. I enjoyed Archer, I enjoyed some of Rick and Morty, but I also recognize that I’d refuse to engage with someone like that in real life. Iasip takes it to the extreme of being genuinely unpleasant.
