The Robot Revolution is a story that succeeds way more at being a companion introduction than an episode in his own right. If Belinda's introduction makes her already a very rounded character, with depicting however briefly her work and home life, and by putting her at odds with the doctor makes for a great dynamic, the same can't be said for the plot proper. There's a lot of good ideas, and the retrofuturistic aesthetic looks really good, making really cartoonish designs come to life and really pop, with very good vfx, especially concerning the weapons and the time fracture scene, it is in service of a story that doesn't take the time it needs. Side characters are barely introduced before being disposed or sidelined. It makes their fate lack impact. The whole story taking the time to establish the (well executed) bootstrap paradox of it all leaves the actual struggles of the missbelindachandrakind an aftertought of the episode which is a complete shame. Same goes for the reveal that feels somewhat preachy and that could have been executed better if done a little more subtly and by trusting the audience a little more to get the message without insisting upon it and getting the time to explore the episode's villain a little more.
