After this post, I'll exit this thread for a while, until Acolyte finishes it's nominal S1 run, to be on the safe side.
Here's what I will say. If all anyone gets from the Acolyte is one season, then I would still call that satisfactory, it's self contained. There are some elements designed intentionally to allow for backdoor pilots into the High Republic timeline and preexisting worldbuilding. From what I've been told, the standard P&A rollout for most everyone else was metered, to prevent some spoilers potential.
What I predict will happen is people will begin to parse down on Headland's interviews, past and present. There are things she has to say, avoid or cover to deal with the practical internal politics of how The Big Mouse works now. That element is not her fault. My take is I consider her a baseline competent industry writer, but her best skill is handling the political side of production. She knows her limits. She knows what she can and can't do ( She understands she's not Aaron Sorkin, she can't write like that, and she can't take those kind of risks) This is pretty fundamental storytelling here, she's not trying to reinvent the wheel. She could potentially be very successful within the current framework of how Lucasfilm operates right now. I consider myself pretty fair about this kind of stuff, if something is good, I'll say it, if something is bad, I'll say that too.
Will there be more Acolyte? Personally I don't think that's a great idea. But this is Kathleen Kennedy we are talking about here. I recognize most people here have not seen Russian Doll but if you've seen that, the Acolyte won't surprise you. Headland, like most high level creatives, only really tells one kind of story. ( i.e. Michael Mann does cat and mouse, James Gunn does underdog dysfunctional ad-hoc family, Marc Cherry does noir style satire, etc, etc) I don't think what Headland does well is going to replicate seamlessly over multiple seasons. But, of course, I could be wrong.
On an aside, congratulations on your new Staff position. Get a helmet though, you'll probably need it here....
