I just went and checked how they ended the US Life on Mars. Woah, that's really crazy stuff. Different, and less nihilistic I suppose, than the UK ending (although since the UK show has a sequel series, there may be more to the mystery than "It was just a coma-induced hallucination,") but still bonkers. It was all a VR-induced hallucination? Hmm.

BSG's ending was not quite what it could have been. The writers lost their way towards the end and seemed to have difficulty satisfactorily addressing all the mysteries they'd set up. That said, there was at least one vague hint that it wasn't God but some kind of space alien. Still weak though, and the "Robots are bad OMG!" ending was over-egging the pudding.

LOST, on the other hand, has been on fire this last season. Its use of time travel has been really fascinating to watch and implemented intelligently (unlike, say, HEROES). I suspect the writers have also got a better idea for the finale in mind than either BSG or LoM had, simply because they've set up all their mysteries ahead of time instead of just making them up as they went along, like BSG.

I take it we shouldn't be expecting R'hllor to turn up, resurrect Ned and then save the day at the end of A DREAM OF SPRING then? :-)
