Disc 7 contains what has often been voted the greatest Doctor Who story of all time. More recent polls might favour some of the post 2005 episodes like Blink or Heaven Sent, but The Caves of Androzani still holds its own as arguably the best of the classic era.
It had a reissue in one of the "Revisitations" box sets, so we've already seen most of the extras.
What we get here new is a version of the story with optional new VFX - the fifth story to feature this on the set.
Other than establishing shots of the twin planets and the Monument Valley-like TARDIS landing site, these effects mainly deal with the Magma Beast and spaceships.
The monster is a lot more mobile than the very static costume, though that hasn't been replaced totally here. It's primarily close-ups which benefit from the new CGI, giving it more animated features.
Model work of Stotz's ship is replaced on a couple of occasions.
There has been a lot of criticism regarding the use of AI in the recent box-sets. This has been used to sharpen the image, but on occasion has interfered with actors' faces.
Its use is particularly noticeable in Part One of this story, in the scene set in Morgus' office where he has his video-link chat with Chellak. Morgus' face loses all movement, the lips hardly matching his dialogue.
Quite unnecessary to have employed this at all, especially if it is actually going to spoil the image rather than improve it. You'll notice the AI in operation on other stories, especially in TARDIS scenes.
Luckily the Behind the Sofa panellists are only watching edited highlights of the regular version, so director Graeme Harper's thoughts on this go unrecorded.
He joins the Fifth Doctor sofa, and unlike other guest viewers so far has a lot more involvement in the discussions about what they are watching.
Everyone comments on how adult and dark this story is, with Aldred and Padbury stating they would have liked to have seen at least a little humour to lighten the mood occasionally.
As a story it is unrelentingly bleak, like Logopolis having an ominous feel throughout. (We go into these knowing that the Doctor is going to "die" at the conclusion, and this mood permeates the entire story in both cases).
Other than the Magma Beast costume, which was never all that prominent in the original broadcast, you really can't fault the story. Casting is perfect for every role - no stunt casting this time; the lighting is kept low and atmospheric; and - despite rehashing elements from the less than perfect The Power of Kroll - the writing is some of Robert Holmes' best. It just goes to show the difference it makes when the same material, more or less, is given to an innovative director.
Interestingly, it's not Davison who gets teary-eyed at the regeneration scene, but Colin Baker, who has nothing but praise for his predecessor's Doctor.
Of the extras we've seen before, this being Davison's last story, they have included the regular stuff like "Tomorrow's Times" and "Stripped For Action" covering the Fifth Doctor era.
That big documentary presented by Davison's son-in-law (what ever happened to him?) is also included here.
This is the last time we'll see Davison watch his own stories. Hopefully he'll be back on a sofa for some of the Troughton ones when they finally get round to releasing them, as that was his favourite Doctor.
