If you're going to skip any of the Eighth Doctor's run, skip this one. It does basically nothing new with the Cyberman, and despite being fairly simple and boring, I still found it confusing at times. There are too many side characters, which appears to be a reoccurring theme in these early audios, and we don't spend enough time with any one of them to garner an emotional reaction when they inevitably die. Even the Doctor and Charlie seem completely unaffected by their deaths.

It has a nice message, but that's basically it's only redeeming quality, and other stories have done it better. It's not horrible and I didn't hate listening to it; it's just not really worth the time.
