K-9 and Company, British
BBC; IMDb; TV.com; Wikipedia

This was supposed to be a spin-off from Doctor Who, but it never made it past the pilot episode ("A Girl's Best Friend"). Which is why I'm putting it in the TV movie section rather than the series section. Anyway, it's about one of the Doctor's companions, Sarah Jane Smith, went back to her old life on Earth after her travels in space and time with the Doctor. And she found a package waiting, which he'd left for her. It was K-9 Mark III. (On the series Doctor Who, the Doctor had at one point gotten a computer dog named K-9 from some scientist in the course of his adventures. The first K-9 later stayed on Gallifrey with Leela, and the Doctor got a second one, K-9 Mark II.)

Anyway, Sarah Jane and K-9 had some odd adventure which involved Druids and Stonehenge, or something. It wasn't all that good, but I still would've liked the series to have continued a bit. One of these days I shall have to rewatch the thing and write up a proper review.

Meanwhile, Sarah Jane has, all these years later, finally got a new spin-off series, The Sarah Jane Adventures....
