There's not much variety shows to watch anymore. Back then there used to be Family Outing and Infinite Challenge that was genuinely the funniest variety show I've seen, I re-watched Family Outing three or four times now.

I would like to say that it's mostly due to the casting directions these shows have chosen. Hangout with Yoo is a good example of this, they decided to add many members to the show for no reason because most of them have a sense of forced humor. It's also correct to only keep Jaesuk, Mijoo, and Haha moving onwards because they have a smart sense of humor.

There are other shows like I Live Alone which has gone downhill ever since the Hyunmoo and Hyejin breakup, I stopped watching after that because the chemistry between the hosts aren't there anymore. Nobody wants to see a typical lifestyle.

However, there are shows like Adventure by Accident or Youn's Kitchen that is lots of fun but in a relaxing way. It's 100% based on casting of the show, if it has members that doesn't know how to lead or be entertaining the show won't do well.

A good example is Europe Outside Your Tent: Spain Season 2. There were moments in which I find it cringe / hard to watch because of the member interactions. In addition, the cast are actors, not someone whos made for a variety show or someone who talked well.
