A fairly fun romp; it takes it a bit to get moving, but the undeniable chemistry (pun intended) that the Rani adds to the Doctor and Master's dynamic is delightful. I could watch them sniping at each other all day. It also gives Peri something to do with her botany knowledge for once. I would have liked for Stevenson to have had a bit more to do with the main plot, but ultimately the historical portion of the episode is about the Luddites, rather than the industrialists.
