Assistants have really gone downhill, haven't they? I mean, back in the day there was none of this 'Daleks! We're all doomed, let's have an angsty moment and do sod all about it.' It was 'Daleks? Where? Let's hit them with a baseball bat and blow them up with grenades! Wheee!' Frankly, I expected better of Sarah Jane Smith. Liked Harriet Jones, though.

And yes, I would have thought having twenty-seven planets in such close proximity would mean instant squish, gravity being what it is. But perhaps there is some plot device going on there to cancel out the squish.

Just hope that everyone who's dead stays dead this time. I'm getting so sick of 'Everybody lives!'
