||An interesting idea, which works up to a point. I did wonder slightly what the people on the Demon Planet would do, let alone eat or drink, after the Voyager had flown off. Once I had worked out what was going on, I began to wonder if any episodes between "Demon" and "Thirty Days" were set on the wrong ship. Unlikely, but possible. Of course, there'll be no references to this in the future (say by the 'real' crew arriving at a planet where the people recognize them). Here, the sense that something was wrong grew on you steadily throughout the first quarter of the episode, and then the ship's deterioration really set in. We've seen a beaten-up Voyager before, but not falling apart at the molecular level. Duplicate or not, Janeway was still Janeway, still determined to press on despite condemning her crew to a very unpleasant death if she got it wrong, then gambling all their lives in a race back to the Demon Planet. This time, she lost, but managed to die in her command chair. Maybe it's unfortunate that they didn't make it, but it provides closure to the events of "Demon". Overall, somehow the Voyager cast always seem at their most convincing when the ship is coming apart around them (which is probably why the writers smashed her up so often). Finally, we have the ultimate Reset Button, none of it happened to the 'real' Voyagers anyway. Verdict, watchable enough. Finally, Paris called Janeway 'sir' on the 'real' bridge at the end, perhaps the nature of the moment caused her to let him off that one.
