I'm probably coming in a little late to this conversation, but I actually really liked 9, 10, and
11. I felt like they all managed to bring something new to the Doctor's character. If I had
to choose I would pick 10, if only because Tennant was the Doctor when I first joined the fandom.
I haven't seen many of the older episodes, but of the ones I have seen, I really enjoyed Baker (4).
Favorite companion? I really liked Rose and Donna. And Jack. River was great, too.
Favorite episode? I really, really loved Blink
, which seems to be a common theme around here. Midnight
was interesting, and I also really liked The Day of the Doctor
and The Time of the Doctor
As for Neverwhere
... I read the book awhile back, but didn't realize they had made it into a series! I'll have to look into that
