Sure, it's unusual in that it was the first ever story set entirely on contemporary Earth (with the regular cast the right size, that is); it's decidedly odd in the casual discarding of Dodo as a companion (when one remembers the angst associated with more recent departures!); it has a significant weakness in that the actual War Machines themselves are a bit crap (though far from the worst robotic monsters ever seen on Who, and salvaged a bit by good directing).
But despite these weaknesses, it remains a generally well-written, well-acted, well-made and likeable story, and the restorers have done a fine job of injecting more life into it. . On the DVD, the informational sub-titles are informative. The Blue Peter extracts (make your own Post Office Tower!) are fun. The film of Tony Benn revisiting it forty years on is almost moving (as is the famous restaurant). The commentary/gossip between Michael Ferguson (director) and Anneke Wills (Polly) is not terribly deep, but they deliver just about enough to justify their fees.
One point they make about Hartnell is that he would sometimes vary his lines. This may explain the slight oddness of his his final exchange with Dodo; I wonder if it is an improvement on the original line from the script?
Anyway, warmly recommended.
