The episode is over in the UK and the Twitter reaction is smaller but very positive. Certainly, most fans thought that Nikola Tesla’s Night of Terror was an improvement from last week’s episode.

Katy Manning was fan of this week’s episode as well as Bradley Walsh!!

Jon Arnold was also a fan and loved the writing and direction
Thoroughly enjoyed this week’s #DoctorWho. Hats off to @ninametivier for a cracking script, Nida Manzoor for some beautiful direction and a cracking guest cast.

The Women of Who love Anjli’s performance and on another tweet there’s something about a leather jacket. 😀
Aw, what an enjoyable episode!
I thought it was very atmospheric, the characters were enjoyable, I *really* liked Anjli Mohindra's performance as Queen Skithra, and the companions actually seemed to get equal screen time – yay!
Overall, a fun little story. Thoughts?#DoctorWho pic.twitter.com/d47Tu8SVS4

Rik Moran — excuse me – The Rik Moran wants more episodes from Nina Metivier.
More episodes from @ninametivier for @bbcdoctorwho please.#DoctorWho

Morgan had a connection with Nikola Tesla’s character.
Wasn't tonight's #DoctorWho just wonderful? #NikolaTesla was probably my favourite historical character to appear in the show to date. The line about him saying how no one understands him really resonated with me too. Perfect. ⚡⚡ pic.twitter.com/qNHVq4vRRi

Watching in Chicago tonight. While I though the Tesla storyline had promise, the aliens are ridiculous – I’m glad they didn’t hire the terrible actress who played the spider queen in the first Doctor/Donna episode but they sure brought hst teeth back!! Did they lose their costume budget? I mean, an alien scorpion who looks like a human wearing black paint…hating this entire season.
