The First Doctor that I ever saw on tv was John Pertwee incarnation . I wasn't able to get into the series, and then one day I turned on the PBS and there was Tom Bakers first episode . Robot. His intepresation of the character had me in stitched. He was of the wall. I loved him in that role. His Doctor could be funny and deadly serious at the same time. My favorite episode with him is Genesis of the Daleks , My least favorite was Logopolis because its good as it was , it was his last series. It was aaasadd to see him leave the show . I got to like Davidson and theses that came after and I went back and watched all he old Doctor episodes prior baker that existed. eveyth act that palyedthe part bought something interesting and new to the role . In Perwee era my favorite serial is Inferno. it's seven part serial and its got everything . parallel universe , , A parallel universe with evil and not evil Doppelgängers of the main characters, a obsessed scientiees and and world end disaster in the the universes. Its classic stuff. !
@BAYLOR like you my first Doctor was John Pertwee, I can remember being terrified by a monster that could walk through walls, I then started watching it regular from the story Planet of the Daleks. I didn’t see inferno the first time round but having seen it since I agree with you that it was a great story, in fact I would love to see it remade with modern sfx.
