While it started as a tiny sitcom that no one watched, It's Always Sunny in Philadelphia has grown to become one of TV's most beloved shows.
Following a gang of self-centred and mean-spirited bar owners, the show's seemingly offensive but secretly progressive discourse and the hectic and absurd ventures the gang get in to has won the hearts of viewers all over the world.
The show is expected to soon overtake The Adventures of Ozzie and Harriet as the live-action sitcom with the most seasons, and fans are begging the show to reach the milestone to justify their love of it.
And now it's coming back, with the 13th season in development despite cast issues and production hardships, and fans couldn't be happier to return to Paddy's Pub and hang out with perhaps the maddest people in the world.
The show is perhaps not returning in the way fans know and love it, however. There have been casting and production changes, especially seeing that the show performs very poorly for FXX when it is aired and does incredibly well on streaming services, especially for Hulu for whom it is one of the most popular shows.
Before the show comes out, and fans decide if they love or hate it, let's run through everything we know about it so far.
