Growing up in Scotland Doctor Who was part of my culture. First Doctor was also Jon Pertwee. I drifted in and out of watching Classic Who, but have been catching up on Britbox - moved to Kentucky, USA in 1999.
My wife and I enjoyed watching Christopher Eccleston, the 9th Doctor. He remains our favourite.
Since then I have watched on Amazon Prime, Max, and now Disney+.
Doctor Who still remains a large part of my culture, and I thank you for this introduction for the benefit of everyone else.
