It's funny and a little sad: Shows that aren't big franchise shows like Farscape, Lexx, NuBSG can get away with stuff like this where they never explain their tech and just have them as background plot devices (if even that). But try something like in Trek where they have an FTL engine but never explain it, crucifixion.
That said, I loved Farscape.
I think nuBSG portrayed FTL the best. Knobs, dials, valves, gauges (Captain's Hand) and then engine things in Season 4. How do they work? Who knows, who cares! "Look, machinery and shit".
