Strangely, when I was thinking about cliffhangers, the Z'ha'dum was at the forefront of my mind. Classic Who ones had to be weekly, because of the show's format, and often tended to be complete-fake outs the next week, because of course, in the days before videos and lots of repeats, one didn't always remember the previous week's climax exactly and they could get away with it!

But with B5 things seemed less contrived. Okay, so I know that whole bit with Sheridan after he's fallen into the pit was a bit daft, but it did make sense in the context of the show, and there was a price to be paid. Moffat has said that DW is going darker this series - which I hope means we'll get to see consequences and get explanations for things that actually makes sense!
