I watched Dr Who from the first show in 1963 when I was 13. I watched it fairly regularly until 1989, but was often in places where there was no access (like university where I didn't own a TV), and I lost interest towards the end.

When it "regenerated" I was keen to watch again, and my daughter was also enthusiastic. We watched until Matt Smith left, and haven't watched since.

We did watch "Torchwood" from 2006, and enjoyed it.

You might want to add "The Sarah-Jane Adventures" to your list of spin-off shows. This was another show I watched with my daughter, who was in the age range the show was aimed at, at the time. I certainly found it watchable myself.

Thanks for doing this. I am looking forward to hearing more!
