I really wanted to love this episode, but the "both sides" handling of the political aspects left a bitter taste in my mouth. I'll start out with the positives. I loved how camp the episode was (The Doctor using a confetti cannon to maneuver himself back to the ship was fun), and the fact that there were songs present and that they were actually good. I have much more to say about the negatives. Although the antagonists had valid motivations, destroying the corporation that committed genocide against their people and planet to make profit from stolen natural resources, they were still depicted as mostly one-dimensional terrorists. Obviously their plan to murder three trillion people is horrendous, but the characters and the narrative equate it to the genocide committed by the Corporation (the corporate sponsors of the Interstellar Song Contest) against the Hellions. Although it makes sense to focus more on the acts committed by the main antagonists, the Corporation's crimes are mostly ignored by the characters. Cora is depicted as the "good" Hellion because she protested within the system (again, I think attempting to murder everyone in the universe is awful and I wasn't rooting for the antagonists), but that doesn't detract from how protests that don't attempt to change anything on a systemic level were depicted as superior, and how one song was shown to automatically changing the minds of most people in the audience. Although I love it when the Doctor shows his darker side, the scene of him torturing the kid definitely dragged on a bit too long for it to be in character. For the rest of the season, Belinda hasn't hesitated to criticize the Doctor (which I love), and it felt out of character that she didn't say anything after she saw him torture someone. These last three episodes have been Belinda-lite, which I don't like since she's a very interesting companion in a very short season that I think I would love even more if she had more time on screen. Susan appearing in the Doctor's mind felt a bit out of place. I already saw the leaks about Mrs. Flood being the Rani, but I still don't like the use of bigeneration. That being said, Archie Panjabi is fantastic in the role! I wasn't the biggest fan of it in "The Giggle" but at least it was a one-time thing that made sense since the Doctor went to the end of the universe and certain forces were let in. There was no reason for the Rani to bigenerate. Additionally, Mrs. Flood suddenly becoming subservient when the other version of herself took charge felt out of character.
