Re: Zygons, I hope they make a special effort with the upcoming DVD release -- it's one of the best stories, and perhaps one of the last of Tom's on DVD (not sure).
Re: the anniversary, it's a mixed blessing. If they include the classic series they can't do it without Tom -- it's as simple as that. No one would take it seriously. And even if they do include Tom, chances are we'll have to have some Sylvester McCoy and 'Ace'. It's like a Christmas dinner -- being forced to eat cold and disgusting brussel sprouts before you're allowed the sumptuous pudding.
"A man's work is nothing but this slow trek to rediscover, through the detours of art, those two or three great and simple images in whose presence his heart first opened."
