I was born in May 1970, so I'm almost as old as the transmitted Spearhead From Space. I didn't see it, though, until this abridged VHS release came out. I knew about the Doctor being exiled, but it was so wonderful to actually see it at last, and the Autons. I was seven when The Robots of Death originally broadcast and recall walking around the school playground, arms outstretched chanting, "Kill the humans." I didn't see it again until the VHS release, which I watched ... to death.
You picked two of the best Doctor Who adventures...they never age ..unlike the current Who....they both hit the ground running and show how good the show can be ..
