I'm giving this episode half a star, and it's all for the Thirteenth Doctor.

I really hated this and I thought it was a complete mess. The main plot was resolved very quickly and easily, and it was a complete waste of the Rani. Being eaten by Omega was so stupid. Omega was also defeated very quickly, and I didn't like his redesign, it was nothing to do with his previous appearances or character.

The exposition during the beginning felt clunky, like the dialogue was being given to each character without any thought as to whether it was something they would actually say.

Anita showing up was nice, but saving the Doctor with a magic door was unsatisfactory and convenient. She also didn’t do much, and could have been replaced by anyone else.

I hated UNIT battling the bone monsters, it was so Marvel-esque, which is not something I want from Doctor Who. I didn't understand the focus on Poppy. Why was she suddenly Belinda's child? Why is Belinda nothing like the character from the season opener? Why did so much of her character this episode revolve around being a mother? Why did Fifteen regenerate when he wasn't injured or dying? What was the point of Thirteen showing up? What was the point of Omega and the Rani, if RTD wasn't going to utilise them properly? There was a lot of exposition (especially at the beginning) and made-up sci-fi explanations that explained nothing and only made me more confused.

I am so annoyed and angry that this was Fifteen’s regeneration story. Two seasons is short and it hasn’t felt like he’s had enough time to develop the character. There is also something uncomfortable about the fact that both the first female Doctor and the first Black Doctor regenerated into actors who have played  very popular characters in RTD’s first era.

I did enjoy the visuals, the Rani's bone palace looked amazing. I also loved the references to Looms, and of course, seeing the Thirteenth Doctor.

But, mostly I was very angry, betrayed, and disappointed.
