Episode 2 of Doctor Who Season 10, “Smile,” featured emoji-faced robots (or not strictly robots), as well as Bill’s first real trip in the Tardis and into (as is proper) the future.

It wasn’t a great story, but it was a good one, and I think it was a great opportunity for character interactions.

Complaints would be that The Doctor was too quick to leap to the “blow it up” solution (shades of Lethbridge-Stewart, maybe); and that the pacing dropped off badly in the last third, with The Doc taking ages to explain things long after it was obvious that he just needed to reprogram the robots.

Still, it was, as I say, great character work — Bill is shaping up to be an excellent companion — and an amazing location. I heard that the main building is in Valencia, and parts of it looked an awful lot like the Eden Project.

I also like that the episodes are continuing one into the next. Will they carry that on through the whole season? Could they? Should they?
