when I said I started on Season 1 I didn't mean the very first Dr. Who.... which started I don't know when. Maybe the 50's? I meant the Netflix Episodes.
So all I know are the actors Christopher Eccleston and David Tennant... with Tennant I can't get Barty Crouch Jr. out of my mind.
My friend who recommended the series to me knows them all.
For the first few episodes I watched I was a bit reminded of the old series "The Prisoner" starring Patrick McGoohan. I never did see all of those but I did see many including the final episode.
