Re: Last Classic Who Story you watched
The crew of the sandminer were human not aliens, that's pretty clearly stated in the story. I rather liked the red herring and the robophobia idea. I also liked it that the Doctor's voice wasn't affected by the helium, that added yet another layer of mystery to the Doctor.
The greatest science fiction series of all time is
Doctor Who! And I'll take you all on, one-by-one
or all in a bunch to back it up!"
