It's giving nothing away to comment on the return of The Doctor's second most prolific enemies; the emotionless Cybermen however play a relatively small part in this audio adventure; it's the reveal at the end of part two that will really get the fans excited.
Legend of the Cybermen is the third in a loosely linked Sixth Doctor series, also featuring the return of erstwhile travelling companion Jamie, whom the Time Lords returned to his own time before forcing Patrick Troughton's Second Doctor to regenerate. There are even more surprises in store than the revelation of where the TARDIS has brought them this time, and the whole play consequently feels warm and nostalgic. That's not to say that the story is bogged down in continuity however, but a new listener could do worse than check out the DVD Doctor Who - The Mind Robber  [DVD
] before listening to this.
Big Finish's consistently excellent production values, coupled with appropriate incidental music and a host of great lines make this an audio adventure well worth investing in; go on, you know you want to...
