Bumping this thread because I've been watching the show again and am about 4 episodes from the end. I think that I missed some episodes near the end because I don't recall some of this stuff (and yes, it's confusing). I don't recall if they stick the landing, but I kind of think they don't. But, I hope I'm wrong.
Anway, despite how old the show is, I think it really holds up well. Probably because they kept the effects mostly practical and they must have hit the exact right time period to have passable but cheap shots of spaceships in space.
