The good: Cyber-lore!

The bad: Really racist!

I can't completely dismiss this story; there is some good stuff in there. The Doctor and Victoria have a beautiful and poignant conversation about loss, there are some real moments of levity, and the iconic scene of the Cybermen pushing their way out of the tombs. On the other hand, the depictions of the villains is really bad. Kaftan is named after clothes, and Toberman... oh, there's not enough time in the day to discuss why Toberman's portrayal as a strong, silent black manservant who is literally and figuratively dehumanized by the narrative is messed up. I think it's still worth watching, but it's an extremely mixed bag to say the least.
