Interesting, and a surprising choice. I'd think they'd play it safe with some Tom Baker initially. It's what they used to play when they had classic Who back in the day.
True! PBS stations which were running the Doctor back in th 80s would only go as far back as Pertwee.
But the truth is, even back then, there was an interest in both Hartnell and Troughton episodes. All any network executive had to do was attend a convention and see how many people attended and sat through the entire version of "War Games." Heck, i knew people who went into that video room with their pajamas on! (They always showed "War Games" after 10 p.m.)
You can't appreciate the latter Doctors without seeing those who went before them and I wish BBCA would realize that we feel that way.
