William Hartnell - the real Doctor
Brought back memories.
Yes the War Machines were hopelessly flaky but it's possibly worth remembering when this series were first broadcast. The Post Office Tower had only just been built.
(If you get this series on the BBC DVD it includes some great documentaries about the period).
Actually my favourite episodes remain the first three series, - scaring me shitless from behind the sofa. They're available (with DSP image enhancement). Favourite lines include the Doctor's grand-daugher being in school "oh, I forgot you haven't decimalised yet" (1963 ish) - or similar, from memory.
This used to be cutting edge science fiction. No I don't work for BBC marketing
