I' m watching this now....and they really haven't changed much in structure, voice and design! Sure, they've evolved, but it's interesting to see that they haven't changed as much as the Cybermen have....And I can't wait to get to them...!! I'm having to start all over in watching from the beginning because 1. I want to and 2. I forgot where I've left off (which I'm thinking was just after The Aztecs....so not too much farther!)
Hahahah!! it's so funny!! Barbara actually put mud in the eye....and then the Doctor (Grandfather) and Ian (Chesterton) started grabbing it and twirling it around....that must have been what set them off and made them the feared monsters they are today!!! LOL!! :p
The biggest thing I remember is the whole issue of "stairs". There's always been the joke about the Daleks not being able to go up the stairs. But then, I think it was Remembrance of the Daleks, I explicitly remember the Doctor running up some basement stairs only to have the Dalek go after him. I will admit, I was horribly scared for the Doctor. The blanket was up to my eyes!
