The main thing that the show does exceptionally well is that it gives all of its main characters the right amount of focus in the story. The show could of simply been all about OJ Simpson and neglected the stories of the lawyers representing him or even the jury but the show delves into these stories and its these that offer some of the emotional and memorable moments of the series.
The story also chooses to focus not only on the trial of Simpson but also on the racial feelings surrounding the case as well as the racial climate that the USA was experiencing.
There is never a dull moment in the show as the various twists and turns in the plot keep you watching. The soundtrack of the show perfectly captures the time period and the use of news footage from the time immerses viewers successfully.
This is a show that needs to be seen not only for the story and performances but also because it shows how TV can be like film without the visual spectacle that shows like Game of Thrones offer. It's just Great.
