We needn't have worried. The three episodes on this disc, while not vintage Doctor Who (they always save the better episodes for the latter part of each season, after all), have plenty to offer. Partners In Crime is a fun way to start the series, primarily concerned with setting up the Catherine Tate-David Tennant mechanic, and allowing the former to dispel many of the concerns aimed in her direction. It's forgettable stuff, about a miracle diet, but is still entertaining, and Sarah Lancashire is a welcome guest star.

Next up is The Fires Of Pompeii, and this is where the action kicks in. There's a little bit of continuing to set up the main character dynamics, but this is the episode that the effects budget was clearly thrown at. With a massive volcano eruption, impressive monsters and a fast-moving plot, it's good stuff.

Finally, a welcome return for a foe from series past, in Planet Of The Ood. This is a well-written story, with some solid monsters in it, and throws in plenty of moral conundrums along the way. Good stuff.
