Doctor Who - Episode 12.09 - Ascension Of The Cybermen - Review
The penultimate episode of a season of Doctor Who can be vary greatly. Usually it is part of a two or 3 part finale. It can either support the finale, or supersede it which is an issue. Take "Heaven Sent" for example. That is one of the best episodes to ever exist. Its follow up, "Hell Bent", does not live up to what "Heaven Sent" set up. So there are two prisms to look at when it comes to an episode like this. The first is how it is on its own, and the second is how it stacks up compared to the finale.
