"Rondel - intergalactic region devoid of all stellar activity"

So how come it feels like we've gone on location to Rondel, rather than Amsterdam? There's certainly a lack of activity in Arc of Infinity - and a less than stellar cast, if it comes to that.

But at least we have a trigger-happy Nyssa, a new look (but, alas, same personality) Tegan and a Doctor who seems to be staining his whites with more than grass. And they're up against a naughty, helium-powered Time Lord, a swarfega-spewing 'mystery' renegade and something which appears to have crawled out of Colonel Sanders' bin.

Couple that with a pair of berks who give backpackers (and indeed bipeds) a bad name and a strangely familiar guard captain, who is the bottom of everybody's favourites list, and you have an uneven start to an anniversary season.

So do Jim and Martin see this story a delicious Edam or a Dutch oven? Listen here to find out.
