Not sure if it’s the most popular thing since I ‘think’ the Marvel shows beat it out, but it’s by far the most merchandisable
Here is the only direct comparison I could find. As you can see The Mandalorian doubled the amount of viewership time despite having one less episode. Disney is not big on transparency these days.
The Mandalorian
As Nielsen did not begin tracking streaming viewership until 2020, the first-ever live-action Star Wars series starts with a leg up on its competition with nine total episodes available following the Season 2 premiere.

Debuting Oct. 30, The Mandalorian recorded 1.032 billion minutes watched in Season 2’s “opening week” (which Nielsen measured as Oct. 26-Oct. 30). With episodes running between 32-54 minutes, The Mandalorian earned 8.38 billion total minutes of viewership throughout Season 2’s eight-week run. In that span, the series averaged 1.04 billion minutes-watched per week.
Season 2 undoubtedly benefitted from the first live-action introductions of beloved animated characters such as Ahsoka Tano (Rosario Dawson) and Bo-Katan (Katee Sackhoff). Spoiler Alert: Luke Skywalker’s explosive cameo in the Season 2 finale was also likely responsible for a season-best 1.336 billion minutes watched.
WandaVision
WandaVision‘s nine episode first season ranged between 29 and 49 minutes per episode. The series premiered on Disney+ Jan. 15 with two episodes (67 minutes total), collecting 434 million minutes-watched in its “opening week” (Jan. 11-Jan. 17). It’s worth noting that the show’s early experimental episodes all in black-and-white were not the most commercial offering in the streaming era. This may have contributed to a sub 400-million minute total in week two.

Overall, WandaVision earned 4.8 billion minutes-watched over its nine-episode, eight-week run. This includes a weekly average of 600 million minutes-watched. Starting with Episode 5, WandaVision saw weekly increases in minutes-watched, likely thanks to the increasing theory-driven narrative that drove social conversation in a way few shows have in recent years. It concluded with a series-best 924 million minutes watched in its final week.
