I have been watching it for years and I have introduced my grandsons to the Doctor as well.

I watched some of the Baker episodes and I liked him. Didn't see that many, before dvr I couldn't find time to watch any series.

I lost track of it after Baker and didn't find it again until Chris Eccleston, I was not a big fan of CE and only became devoted when David Tennant took over. He is still my favorite but Matt Smith did a good job.

You and your granddaughter will enjoy catching up. No need to go back and watch the older ones unless you really get hooked. I just hope the older guy, who is taking over from Matt, can fill the shoes.

For some reason the new regeneration always seem to work well enough to keep the ball rolling.

BTW, The one actor that I would dearly love to see in the role is Hugh Laurie. House was my idea of the perfect Dr Who. Sadly I fear I will never get my wish. However, in the close knit almost repertory troupe of British actors it is not impossible.
