The Legend of Ruby Sunday

The characters hardly left UNIT, there were minimal special effects and other gimmicks. The entire episode was just a concentrated blast of enthusiastic actors with an incredible script.

Gatwa has found his feet. He has just the right balance of incredulous, wide-eyed wonderment with an occasional bout of anxiety, fear even. To me, this is the Doctor, a person with immense power too aware of the peril that follows in his wake. Gibson was great, delivering a warm, fun character that does not feel over the top.

My only annoyance is repetition. In a few previous episodes the same line is delivered over and over, "space babies" for example. The same happens here with "the trap." It is annoying enough to bump you out of the story's flow.

It's a two-part story, following the season arc of Ruby's origins. Although I think they might have trouble wrapping this up in one episode and expect aspects will follow into the next season. The reveal is coming too late. Either way, The Legend of Ruby Sunday sets up the next episode perfectly.
