I watched it. It wasn't spectacular as it did what I expected it to - introduce us to characters both old and new. The story was weak, the script preferring emphasis on characterisation in lieu of plot but I expect that the further twelve episodes will improve as we will now be aware of the characters.
There were some silly moments where you have to ask yourself why it was allowed in the show - although a true Doctor Who fan will grin and bear it; we're used to cringeworthy monsters and aliens.
The concept of the show was good. It gives us a chance to enter the world of the Doctor from the point of view of his assistant. It lets the new generation of fans slowly into his world too.
It was good to see a classic enemy from the Jon Pertwee era (Spearhead from Space story) used although a two part pilot, like Star Trek, Stargate, and other science fiction series have done, would have been more appropriate to ease us into the new mythos and to make a better plotted story to begin with.
Ecclestone will take some getting used to - his delivery is fast and overly comical. I expect this to become more subdued as the episodes are aired and the plot takes centre stage.
All in all, three out of five. An An Unearthly Child for the new millenium.
