“War Crimes” says trans rights, but sadly it is also a story by Simon Bucher-Jones so ultimately it is saying nothing.  There is the hint of an interesting idea, but like “Model Train Set” this is a short character portrait with the evolution of a creature being a parallel to the Doctor, Jamie, and Zoe stuck right near the end of The War Games.  It’s fine, honestly kind of bland and has the usual Simon Bucher-Jones thinking he’s actually saying something with dense prose.  5/10.
