This episode would get one star from me, simply for starting the whole darn Doctor Who franchise in the first place, but gets another star for the fact that it probably produced a better fight-scene amongst those cavemen in '63 than anything 'Who would ever subsequently see. This episode also presaged the cheap special effects of future years with the BBC's effects budget being saved a bundle due to the chameleon circuit on the Tardis ever so conveniently "breaking" leaving the good old blue Police box to be recycled for all future episodes. Uh huh.Oh, and if this took place today, with a (supposedly) teenaged girl living in a junkyard with her eccentric "Grandfather," Ian and Barbara would be dialling 999 on their mobiles, and a very different story it would have been indeed...- M.
