If I've got one wish for Chibnall's era of Doctor Who, it's that he learns from the Moffat era not to do any big arcs. RTD's Bad Wolf and Torchwood arcs were simple and subtle. They paid off in the end but weren't too important along the way. Moffat came up with big, intrusive arcs that came with big, messy payoffs. They were like drawn-out Brannon Braga Star Trek weird shit episodes: come up with something crazy then work backwards from that, creating a story that doesn't actually make much sense when you think about it. I'd be happier with a bunch of good standalone episodes.
Props for the Moffat-Braga comparison. I've been making that comparison for years. The two are more similar than Moffat's defenders would care to acknowledge. Moffat is better than Braga at character moments, while Braga is better than Moffat at structure, but their storytelling sensibilities are eerily similar, and they have similar flaws such as mistaking density for complexity.
I would also like to see the season-long arcs go away. Besides my feeling that Moffat never understood how to pull off season-long arcs (which surprised me coming out of Jekyll), the arcs have made Moffat's seasons feel "small" in a way that RTD's seasons didn't. When I think about David Tennant's era, I feel like he was the Doctor for a long time. When I think about Matt Smith's era, I feel like he was barely there. In truth, the two eras were almost identical in length. But they feel different because of the nature of RTD's storytelling compared to Moffat's storytelling. RTD's storytelling had room to breathe, while Moffat's doesn't.
But while an end to season arcs is my personal preference, I can see the BBC saying to Chibnall, "Serialized storytelling is the way genre television is done now, and that's what we want from you." I think Chibnall and his writers room will be able to deliver that, but it will be a very different kind of Doctor Who, just as Discovery will almost certainly be a very different kind of Star Trek.
