Exterminate...?

The new "Dr. Who" series seems to have garnered general praise, but for me, the jury is still most definitely out. It is perhaps unfair to make a judgment on the basis of just two episodes, but I have found them both somewhat unsatisfactory. The plot-lines have been disjointed and confusing, and I'm not at all sure just how Matt Smith as the new Doctor is playing the role. He comes across (to me at least) as a kid with a new toy that he is desperate to show off, but hasn't yet got the hang of just how it works. And his new assistant? If he's playing big kid, there are dangerous signs that she is becoming his nanny. Hasn't worked for me so far.
