Over on Blogcritics, Matthew Milam has expressed his opinions about the new season, although it'll take someone with more intelligence than I to figure out exactly what those opinions are:
When Tennant took over the role from Christopher Eccelston (who did the Doctor for Series 1) in "The Parting Of The Ways," it finally seemed like an actor had stepped in with enthusiasm and interest in the character. As luck would have it, we got our chance a few months before Christmas with the mini-segment "Children-In-Need" special. Now with this excitement and joy with a new Doctor at hand, we had to deal with whether the result was worth it. For the CID special, I didn't feel it.
