Tonight's episode "The arc in space".

There's a serious fan base for Dr. Who. It always came on late Sunday night, and was kind of the last hurrah before school on Monday morning. There was nothing else on Sunday night, so it had no competition. In today's day it would be competing against "The walking dead" and "Game of thrones." Many good actors have played the Dr., but I always think of Tom Baker when I think of Dr. Who.
