As someone who was not born until 1972 The Tomb of the Cybermen is a fantastic piece of late '60's TV and the only complete classic Patrick Troughton story to survive the mass junkings of the 1970's (his other surviving complete stories are no where near as good as this).
The story is set on the home planet of the Cybermen in the far distant future where the Cybermen are just archeological relics to be discovered and studied, having been extinct for sometime. The Doctor, Jamie and the new companion Victoria stumble across the archeological team who have just discovered the entrance to the Ttombs. From there they whole group come to discover the delights and horrors waiting for them in the Tombs.
Patrick Troughton's Doctor is a relevation to me personally. He is both restraining and gently cajoling to the archeological team, giving them the answers they want to revive the Cybermen, but viewing the unfolding drama with fascinated horror, one moment manipulating events in the background, the next taking charge. There is some great interplay between the Doctor and Victoria too. And the scene of the Cybermen being thawed out from the impressive cocoons still sends a shiver down the spine 35 years on. Yes there are one or two dodgy special effects but you can see how this terrified children and adults alike in 1967!
This is classic stuff (without giving too much away). The quality of the picture and sound is great and the little documentary on how they restored the episodes (splitting the picture showing before and after restoration)shows how much work was put into this release. All the other extras are great to see but the highlight is the 8mm footage of the special effects ending of the previous story 'Evil of the Daleks' (no longer in existence bar Part 2) matched with the actual soundtrack of Part 7 with the Daleks being blown up left, right and centre.
Lets hope that more Doctor Who DVD's are put together with the care of this one, with more restored and digitally remastered prints, particularly the Hartnell & Troughton years. And lets hope they find some more classic Troughton stories currently missing because if they are anything like this then they deserve to be found!
