The Tenth Planet... 2! (or should that be the Twentieth Planet?) Base under siege story. The Cybermen are here. We know how this one goes by now.

The Cyberman motivations were somewhat interesting, but I'm not a fan of the new designs. The old ones looked cheap but in a way that got across that They Were Once Humans; the new ones just looked cheap. Polly had a couple of good moments, but mostly got reduced to making the coffee. Jamie got knocked out in a manner that I can only assume was to free the writer from having to deal with putting a historical character in a future sci-fi setting. The Moonbase was fine, I guess?
