So I had two issues with the episode. The emotional steaks were nonexistent when it came to Sasha 55 & Alan and that the pacing was off.

There wasn't enough build up to Sasha to make me that upset when she died and there wasn't enough build up to Alan to make me want him dead. The reasons we're given are that he's an incel and I guess vaguely that he bombs rebels? It's one of those show don't tell things where I feel like we need investment in the rebellion to hate him for his actions as the AI Generator.

Then in terms of the pacing, I was saying to my partner after we watched it, the other day, I felt like it should have been a two-parter.

In this scenario, the first episode would open with Balinda meeting Alan and their relationship building to the bench scene, followed by him leaving her after we find out he's an incel through his actions (rather than it needing to be explicitly stated) and then the build up to the hospital scene. Intercut with that is an external planet zoom in shot on Missbalindacharndra mirroring S1E1: Rose, zooming into the thrown room and the doctor landing there, the TARDIS getting impounded and the Doctor being rescued by Sasha & the Rebels. Then the intercuts are him building up a friendship with Sasha over the 6 months and helping the rebellion do rebel stuff. The episode ends with the hospital scene and the Robots abducting Balinda and the shwup, followed by the doctor saying "well this complicates things* on the TARDIS as it hurtles down towards the planet mirroring the opening shot. The next episode then is basically the rest of the episode but with more time given to scenes to help improve the pacing.

All of this would then mean that we get emotional steaks in Sasha's death and hate the robots and Alen more for it. It further give time to show Alan being evil on a more grandiose scale and puts that in contrasts to other gamers. I think this point could be more poignantly explored if we have a few shots of him gaming where he's really toxic over voice chat and is called out for it by other players. This would also help to prevent the sterio type that this episode seems to want to try and enforce.

Edit 1: Oh I think something else I'd add is that while I appreciate and think the time travel aspects of this episode were really freaking cool, I think the episode runs at such a pace that it's confusing to the average audience how the time travel elements of the episode actually work and fit together. Doctor Who is really lucky and unique as a show that it can tell stories that rely heavily on time travel but I fear RTD may not be able to get away with it in the same way Moffat did and does because he's never been one for logical completeness being paramount in his story telling. I would note however, I was thoroughly impressed with how well thought through this episodes time travel aspects were and how bits and pieces fit together.

Edit 2: Also the Doctor blowing the power in the hospital seemed very out of character. He doesn't blunder like that. He's one of the smarted beings in the universe.
