The Children Of Earth five-part special was so successful that... they're not going to do it again. Well, for now. Instead, the BBC are bringing Torchwood back for a fourth season of 13 episodes. John Barrowman made the announcement as a guest on Steve Wright's afternoon radio show. I'm glad, really. I liked COE, but I don't think it filled five hours that brilliantly, and I much prefer the idea of 13 individual stories (with a few two-parters, say.) Maybe we'll just get five-part specials whenever the Torchwood team need a break? It's a good way of allowing busy actors like Barrowman to do other things, without being indefinitely tied into Torchwood every single year.
