Down from five planned seasons to three and eventually two. The second season was also filmed with a crew about a third the size of season one. Plus, they got a $129.3M reimbursement for filming in the UK. Taking down costs to $515.7M. As a result, it didn't go over budget unlike Acolyte.
Now, I probably should've clarified I meant performing in the broadest sense. Not just viewership. Budget obviously played a role in the decision to reduce the amount of seasons for Andor, but audience engagement, demand, and LF's own faith in the project also kept it alive.
Andor was performing well in these metrics, whereas Acolyte stumbled out of the gate. Again, that brings me absolutely no joy. I wanted Acolyte to work. Star Wars needs new eras of storytelling. I've enjoyed the High Republic books and comics I've read. Yet, I also have to be realistic.
