UNIT: Extinction

Big Finish's first release to be focussed solely on the modern series, after they gained the license in 2014, this is a 4-part release that comprises a single story. Kate Stewart and Osgood are the central characters, joined by three newcomers to fill out the ranks. And what better way to kick off a series about UNIT than with the return of the autons, which also heralded the dawn of the ‘UNIT era' proper back in 1970?

The result is, in some respects, a modern updating of Spearhead from Space, with 3D printers and fibre optic internet connections joining the deadly mannequins. There are, of course, plenty of references back to the original series, with the Brigadier being mentioned quite a lot, but nothing that is likely to get in the way of the story for those only familiar with the new one; the only plot point that does rely on a TV episode relates to Rose.

Redgrave and Oliver are both great in their roles, bringing their TV characters back to life. The new captain and lieutenant show promise, although as yet there's little to see in Colonel Shindi, who mainly takes the Brigadier's old role of promoting the military solution. There's also a glossy, modern feel to the story, enhanced by a good theme tune.

The first two parts of the story are probably the strongest, although the second one is unusually short (37 minutes, rather than the usual 45-50). The latter half is, perhaps inevitably, stronger on the action, something that would look spectacular in a properly done film or TV episode, but can sometimes be a little confusing on audio. But even so, it manages to be engaging, with a fast-paced story and some good use of Osgood as scientific advisor. Despite the combat, this does have something of a DW feel, blending some of the original UNIT era's action-oriented style with a modern series aesthetic.

This 4.5 stars rounded up, rather than the straight five, since the story arguably doesn't have any great depth. But it's a great launch to this new spin-off, allowing us to see Earth under threat when the Doctor isn't around, and setting up new characters for the future.
