Your thoughts are very similar to mine. Overall I enjoyed it, but felt it was seriously flawed in places. In particular stories 3 and 6, with far too much exposition and confusing split storylines. Which is an ambitious thing to try, but didn’t work well in the limited time we had available. I also wish more things had been streamlined out eg I was much more invested in Storm and Azure as baddies than the sontarans. Kate Stewart might as well not have been there, and the Grand Serpent was underused. And I’d have honestly been happier if Bel and Vinder *had* been the Doctor’s parents! But overall yes a huge step up for me on previous Chris Chibnall written stories, and an ambitious but somewhat flawed experiment.
