I really love the villain, he’s introduced as this very intelligent character from the way he talks, but as he talks more it’s obvious he just has a massive ego and wants to seem smart. His whole thing is that he wants to stop a future war with his alien race and the earth by fixing all the earth's problems in the past, but the way he goes about it is insane. He has an army of women for some reason and he thinks blowing up the moon is the best way to stop the space race.

The story wants to convey that it is wrong for one person to play god in this way, that even if his plan did work, it would still be taking away humanity's own agency by not letting them make their own decisions and mistakes. I think that’s sort of dumb, all of humanity didn’t decide most of the things that Igrix wants to prevent, those were the decisions of the government. The doctor is telling rose “what do you think of a world where an alien prevents the vietnam war, and ends poverty and famine and all the world's problems” and she’s like “that sounds unethical, that means taking away all of our world government's agency, they chose to make the world worse and to take away that choice from them, give them only the choice to make the world better would be wrong” i don’t know, i disagree. Overall, fun story but it was written by Gareth Roberts so it just leaves you bit confused.
