OK, no major spoilers, just the usual first reaction thingy.
Fun. Lots of major silliness, great gags, yet another fiendish alien invasion attempt, and a proper resolution of the last Christmas episode.
And for anyone having doubts about the return of Matt Lucas as Nardole, yeah, you were wrong. He turns out to be much more than a one-note comic character, and I’ll be interested to see how he develops in the new episodes starting in the Spring.
A more detailed thingy may follow when I’ve watched it again. Depending on tuit supplies, as always.
