Doctor Who: Autonomy (audiobook)

The Doctor was on form as usual, and his temporary companion Kate was above average (I have been unimpressed by the temp. companions lately). She was clever, calm and helpful and was not easily impressed by the Doctor's propensity for showing off, but she was also not an obnoxious know-it-all. The two teenagers were not so great, especially the whiny Rhys, but this was probably exacerbated by the intonation given to them by the narrator.
I've noticed that the alien invasions tend to be a little more straight-forward than those plots in which humans are the actual threat, but the plotting was still well done with good, solid build-up and inventiveness. I particularly liked the White Queen from Narnia making her appearance in the form of an Auton in the Winter World, and the attendant references to lampposts.
Overall: 5-star Doctor Who
good setting with many possibilities
above-average temporary companion
excellent use of the medium to transcend effects budgets
strong plotting
Doctor well characterized
minor note: audiobook sound quality a little muffled and uneven
only real weakness: straight-forward threat, with predictable solution (if you've seen the Autons on the show)
