I know it's mostly spin but Russell says everyone is happy with the ratings the series is getting, particularly with the under-30 age group, which he was apparently asked to make the series more attractive to. (Hence Gatwa instead of Capaldi Mk II presumably.)
On the positive front tThe Live +28 numbers have continued to grow, with Episode 1 adding another 1.6 million over the Live +7.

Think I caught sight of a break down where 7-14 viewers are basically non-existent though. At this rate they’re gonna have to dump a truck of cash outside Matt Smiths house for the 25th anniversary of the new series, and course correct again. (Smith was def popular with the kids at the time)
Eight episodes is too short, two with little to no presence by lead actor throughout, and inconsistent costuming, it’s not enough to be a base to grow off.
