The Pertwee era is my favourite from Doctor Who - although the Tom era runs it close. The Daemons epitomises my first-hand memories of the show when I was a child - the Doctor/Jo pairing, the Master, Unit, but all fans of the show will know the plot.
The restoration is a step up again from the previous attempt 20 years ago - advances in technology having made this possible. For the first time, we see the raw material they had to work with and appreciate how much work has gone into this. See the decidedly mediocre picture quality on the Tomorrow's World clips, the terrible picture sparkle on the closing stages of the restoration test, and hear the wobbly sound particularly on the closing credits !.
To be picky, in general I think the location material looks a little inferior to the parts recorded in studio - just a little grainy, but nothing to worry about.
The extras are very well done. It's a pity that rights issues prevented Return to Devils End being included, but in its absense a nice "making of" story has been assembled - featuring some of the surviving cast and crew (but why no Stephen Thorne, who gave a good contribution to the recent Three Doctors rerelease ?). The tribute to Barry Letts is a fitting one to the late producer whom Who fans have much to thank for. And like the similar Hinchcliffe feature from the recently-released "Android Invasion" it prominently features his children, who knew him best. Some nice colour film from location,
the Tomorrow's World feature and colourisation test I have already mentioned and the usual photos and trailer (in this case for Nightmare of Eden) round things off.
