Ooh, I'm not a Doctor Who fan, but I love Youtube tributes. I'm always so impressed at the time and creativity that go into them (plus they totally suck me into their worlds!) :)
Yes, some fans are so great, to create these YouTube clips.
I liked Rose too I have to say. Hmmm, if you like Billie Piper, you really should check out her starring role in the UK series "Diary of a London Call Girl". It's very naughty, which should mean it's right up your alley. :-)
I've watched her other TV movie, about a ruby that has gone missing. It was a great one. I think the new Doctor Who was in that TV movie too. But for Diary of a London Call Girl, it's often too late in the evening for me...
