I would say the premise was a really good one. Lone lost ship far from home, doing whatever they needed to do to survive. There is so much potential there. But then they did Voyager instead.
Totally agreed. I thought it was pretty great from a concept standpoint. But they disappointed in the very first episode, when the big ongoing villains' motivation was that they didn't know how to make water from hydrogen and oxygen. My suspension of disbelief is mighty, and I am capable of purely enjoying things that have bad science or even bad plotting (I very much loved the Trek reboot, for instance, despite recognizing a rather large list of flaws!). But that pilot just reeked of utter contempt for science, science fiction, and intelligence among viewers.
Now, Battlestar Galactica (the new one, not the original) is a show that I think is similar in concept (in the first episodes, especially, there was a tremendous focus on conserving and finding resources) but fit the descriptor of
"started off good and progressively got worse as it went on" (I didn't see much of the last season, though, and I will note that the Season 3 opener was pretty fantastic, if not the rest of the season). Actually, Lost felt like that, too. And I'm pretty sure I enjoyed Gilligan's Island more in its starting phase. Huh. Maybe it's just Voyager that's the odd show out in the
"Hey, we're lost, maybe we should start scrounging for resources while looking for [a] home" genre.
