...When the Doctor gets activated in an Alien civilization 700 or so years after Voyager appeared there. You know, the one where voyager is a warship. The story was great, the premise was great. But ending it with the Doctor heading out to space to get back to earth; for the next episode to have the doctor in was just a total disservice to fans. He should have been removed completely from the crew (with the episode reflecting back on the previous episode on how the doctor was lost) or it should have been a temporal episode of sorts of how he got back.
But for them just to carry on as normal, with no mention of it was just plain shit
