The show still seems to be aiming in the same direction as the previous season, though thus far, it's nailing the execution a bit better. Still, I'm not thrilled with this new lore-heavy, continuity-light approach. Riffing on prior years (and decades) of the show, but ignoring or leap-frogging what's more recent, I feel like it muddles theme and characterization. Like, I felt like the Moffat years were in dialog with the RTD years, but it's starting to seem like Chibnall's era is a bit more "Classic Who, tell the Moffat/RTD eras I liked it better when the Master shrunk people," while they're all sitting around the same dinner table.
Like, one of the major arcs for the Twelfth Doctor was learning Memory Wiping Is Serious Business Not To Be Taken Lightly, both with what happens with Clara, and the fact that him still being hurt by it is why he decides to start traveling with Bill when she unintentionally called him out on it, but now the Doctor is back to doing it like it's no big thing, probably more casually than ever. Saving Gallifrey was set up as the Doctor's crowning achievement, their greatest act of heroism reaching across the length of the show/his life, and now it's undone as a mystery hook, and we're back to the Doctor making glib excuses when companions ask to visit. The Master had a huge arc very recently, and there isn't even a meaningful glance alluding to it.
And it'd be super-easy to turn the Master bad again! All the pieces were already there; the Doctor was guarding Missy on the grounds that even a totally-for-sure-dead Time Lord could, conceivably, still regenerate. Say Missy was there on the Mondasian ship on the edge of death for centuries, slowly going mad (again) while stuck in her own head, blaming the Doctor for not coming after her after his big speech, boom, Master is evil again and the Doctor gets to feel guilty about it. Dribble it out a bit, let that be a mystery rather than having another damn arc-word.
