It starts with a pretty good focus, on cruel Victorian “freak shows” and leading scientists from the Enlightenment period. It unfortunately devolves into stand offs with random aliens who seem disconnected from these initial focal points.

It is notable that The Doctor never denounces the demonstrable practice of people with physical differences being kept in cages for other’s entertainment. He even delivers a previously caged individual back to the circus once they are saved. This does not feel like the Doctor we know and love.
