The one I was least excited about, the one that has surprised me the most, for good. Great plotwist mid-way through (I kinda saw it coming, but was surprised nonetheless), amazing character work for Ruby, for UNIT and specially for Kate (she was amazing, I'm excited for the spin-off now). It tackles political and sociological topics extremely relevant in our time (fake news, the spread of hate and fear throughout social media in order to rally the masses behind far-right movements...)

Yeah this was amazing, I'm starting to see the theory that Pete McTighe could be the next showrunner as a good thing actually.

Edit: almost forgot, Ncuti at the end! I love when this Doctor goes dark like in Joy to the world.
