I started watching Dr who when the reboot was 3 seasons in, I think David Tennant was the greatest doctor. A few years later I finally got wife to give it a shot as I started a fresh rewatch in preparation for Matt Smith’s second season, she was ok with Eccelston and Tennant but Matt Smith is far and away her favorite doctor. Does this pattern hold true for any other Dr fans?
Your theory kiiiiinda works for me. I started watching Classic Who, and the actor I started with is my favourite - Tom Baker.
I’ve been watching Nu Who from the beginning, and my favourite out of those actors is Peter Capaldi.
