It's Always Sunny absolutely takes inspiration from Seinfeld.
They're even self aware about it in the episode "The Gang Does a Clip Show" where they mistake a bit from Seinfeld as one of their own memories - https://youtu.be/fCwI3KDGtRk
How did you like Mythic Quest? I'm really glad to see Rob and Charlie involved but it's definitely a bit more tame. I really like Danny Pudi playing a Dennis-esque character and the actress who plays Poppy is hilarious.
I really enjoyed MQ. It is ridiculous but also quite true to life according to my wife who is a video game producer. A lot of big personalities, egos, etc.
I loved F. Murray Abraham's character. Quite the departure from Dar Adal in Homeland. Overall the whole cast on MQ was very good though.
I never watched Seinfeld or Curb Your Enthusiasm however I grabbed season 1 of Curb two weeks ago as I am in lockdown and wanted something different/new (to me) to watch and fell in love with it.
I am now on season 8(!) and there hasn't been a single episode I have not thoroughly enjoyed.
It is a superb show with some excellently executed jokes. Probably some of the best I have seen on TV. Some of the jokes are so superbly setup as well that you don't realise until the punchline drops that the build up has been several episodes.
I also watched Mythic Quest earlier in the year which was a lot of fun. We mostly watched it because my wife is a video game producer so we had a good time laughing at how real some of the craziness can be in the video game production world.
Avenue 5 took a while to find its pace but by the end of the season it was quite fun. Different but well done. I am looking forward to season 2.
I plan to sit down and watch Always Sunny, Veep and Seinfeld now :)
It's Always Sunny in Philadelphia on FXX, Hulu, Netflix
Mythic Quest on Apple TV+ - created by people who work on It's always Sunny
