9. Atlanta
A show that defies genre, Atlanta was already one of the most unique shows on TV during its first season, but over its next two seasons, it continued to redefine itself. Created by and starring Donald Glover, the series used everything Glover had learned from writing and acting in comedy to give us a social satire about race relations and the issues that come with fame that was hilarious and thought-provoking from its very first episode. With a stellar cast of names that get more famous by the year and that have great chemistry with each other, Atlanta didn't have to deviate much from what it did during its first season to make an impact, but it did, anyway, propelling it from just a very good show to one of the best of all time.
If Atlanta had anything resembling a formula by the middle of Season 2, it was thrown out the window for Teddy Perkins, arguably the show's best episode. It didn't have too many ha-ha funny moments, and the show's central characters Earn and Alfred had virtually no part of the episode's plot, but it thrived despite that. Now secure in the knowledge that it could completely ignore what had worked before to tell the stories it wanted to tell, Atlanta became more of an anthology series, a Black, Black Mirror, in its third season, which aired earlier this year after a four-year break. Atlanta's more than making up for lost time by premiering its fourth season next months, and the only expectations we can have going into it is that the expectations we will have will be subverted.
