I had to look up Peter Hoar and, mea culpa, he did that episode of "Last of us"... I think we're in good hands.
Some of the episode titles make me unreasonably curious where this is going. "The well"? Please be a deep reference to The ring, although I know it won't be.
"The story & the engine" sounds like writer's jargon, and could be an interesting metafictional take. But again, probably not. Maybe it's an update on the Land of Fiction from the Troughton/Hines run. That would be lovely, and cause for another Tale from the TARDIS.
"Wish world"/"Reality war" — after last season's less than epic finale I'll reserve judgement, but it does sound cautiously promising!
