Most of the theories were getting there. My theory holds for the most part. I was wrong on the: world for all, it"s apparently coppers only. But I was right on the Gene knows, but he forgets. It"s what this world makes you do: forget...
About the ep:
I like the ep, but the ending not so much.
As much as I liked the individual backgrounds (seeing Shaz and Chris die such pointless deaths was hard, and Ray"s suicide: just harsh :s), and Alex final story (I died at 9.06), the ending with Gene staying behind was less satisfying. It seemed like they were saying: well it"s really all about Gene, so who cares about Sam or Alex. I liked the idea of Gene still not being over his death (was him seeing his younger self and startling at the end a sign that he" starting to forget already?), but it was executed wrong.
I also appreciated that the religious scenery was kept ambiguous. You could interprete the elevator going down as going to hell and Keat"s awful hissing as hellish sounds, but it was never stated as a fact. So you can still choose not to go with Heaven-Hell. Although it was laid on pretty thick with the white light in Nelson"s bar, but yeah.
The part in Lancastershire, with Gene"s quiet confession was just beautiful. I really felt for him, young sod, 20 years-old, dying such a pointless death. I can really see why someone like that would like to keep living on in his own fantasy world. Same for Chris and Shaz: such stupid ways to go. With Ray, well he"s finally proved to himself he isn"t useless, so that"s nice too. All of their stories got a good conclusion.
That"s why Alex" passing on seemed so strange to me I think. She only just died (I guess that"s what the watch means? - she"s still living in that second?) and she hasn"t had the time to come to terms with that, I think. Or Molly. She got over it way too quick. All right, she never needed that extra moment of aha-erlebnis, like the others... but still.
I would have preferred to have seen her choosing to stay, like Sam. Perhaps in seven years they could have passed on together, Gene finally having grown up. (Seriously, the insinuation is that he still acts like a 19 year old, why doesn"t he get the chance to learn?)
So all in all: great series, lovely season, perfect episode, but next time I watch, I"m pressing stop right after Ray, Shaz and Chris enter the pub :)
