I didn’t have any problem with Omega’s appearance - his whole deal was that he could reshape his universe at will, so…sure, giant bone monster, why not?

How easily he was dispatched is another matter. It’s sort of what I expected from the episode, but still not exactly satisfying.

“There was plenty of fuss made about Winston Churchill being in Doctor Who, when there’s plenty of history to suggest he wasn’t such a good guy. And that’s always the way.”

He added: "Our history of slavery, our way of walking through the world is constantly being re-analysed. So I like to think it’s the same on Gallifrey… Omega has been re-contextualised, and the story gets bolder and changes over time.

“We don’t want to repeat the past, we want to push it forward.”

This seems like a very odd train of thought, though.
