Maybe they should have thought of that before they let him fuck it up so much. One reason I was reluctant to give credence to the Ianto rumours were that I assumed (especially with such a short season) they'd want a stable format for the show for a while. Carry the old fans with them let the new ones know what to expect. Not crash and burn.

That's somethings that's bothering me as well.
I mean, it's been said all along (mainly by the actors at convention appearances) that good ratings for S3 would make S4 more likely. Presumably the BBC actually want a 4th season. So you'd sort of think that somebody would have looked at the script and gone "uh, what do we do in S4 after that ending?"

(then again, they presumably wanted a 4th season of Robin Hood, and look what happened there)
