It's Always Sunny in Philadelphia

I just finished watching the entire series over the course of the year, so I’m a late-blooming fan. Probably top three comedy show for sure. Seinfeld for Xers and Millenials but with more heart and cast chemistry. It’s amazing that they were able to maintain the quality for the most part through the entire series. Dennis takes a mental health day season finale of the most recent series was fantastic!

I’m curious, why do others connect to and enjoy the show?
