This is great stuff! What's not to like - the Second Doctor at his `Puckish' best, Cybermen, UNIT (with the straight up and down Brigadier, and good ol' Benton) - baddies, helicopters, Russian missiles and everything! Action packed is the only way to describe it - in the course of this eight part story, the Doctor and Jamie scale rope ladders to helicopters, travel around in an RAF Hercules, are involved in UNIT's battle against the Cybermen (with the help of missiles), clamber around the sewers of London in search of Cybermen, climb up elevator shafts - it's all quite exhausting. This is absolutely classic Doctor Who in every good sense of the word. Totally recommended, and totally wonderful.
Frazer Hines does a great job with the linking narrative, and his interview at the end of the third cd is great reminiscing about his enjoyable time with the Doctor, Deborah Watling and Wendy Padbury - I especially like his story about the Wendy Padbury meeting up with the vicar in the Church hall. And Kevin Stoney as Tobias Vaughn is wonderfully chilling - very reminiscent of his ability to ooze evil with every syllable which he showed in his role as Mavic Chen in the First Doctor story with the Daleks.
This story also celebrates the creation of UNIT - although Lethbridge-Stewart and the Doctor have met once before, it was before the creation of UNIT and it is in this story that UNIT really comes into its own.
Cannot recommend this highly enough - would give it 10 stars if I could.
