It also feels odd that we never see the colony. Even just a city shot while Janeway gives her Captain's Log speech about it being amazing would have done.
Yeah, I would have been happy with a Rigel VII style painting shot. Something to see just what kind of city they did build, to let the choice the VOY crew show us what they left behind.
And what if half the crew had wanted to leave? If enough knowledge and skill had left that Voyager was seriously compromised?
