Betty mentioned, in Andromeda's favour:
IMO it's a lot more hit-and-miss than _Farscape_, but I'm getting to like it better and better as time goes on. If nothing else, the fact that somebody on the writing staff obviously has half a clue about the science earns it my respect.
But sadly no more than half a clue about Latin. "Una Salus Victus", indeed. A third-former would know that Victus (nom. sing.) didn't fit in that construction; I've checked the quote, and it's "una salus victis (dat. pl.) nullam sperare salutem (the one [sc. chance of] safety *for* the defeated is not to hope for safety). It's correctly attributed to Aeneid II in the episode guide, but still spelled incorrectly. I just can't believe anyone would be so daft as to use a foreign-language quote and not check it.
OK, there is a fourth-declension noun victus, which is also victus in the genitive, but it means nourishment (victuals), so that would mean the High Guard's motto was "the one chance of getting something to eat". This has a certain appeal, but I don't think it's what the writers intended.
Sorry, end of rant.
Apart from that, I belong to the Andromedan minority, as long as Tyr is written properly. There are some episodes where they completely forget to supply him with self-interested motivation. When he's done right, that sense of melancholy can even make me overlook those ghastly muscles. Oh, I meant to tell you, Betty, I saw a Tyr Anasazi bear on a stall at Eclecticon. The maker told me it wasn't quite finished - no Nietzschean forearm spikes, for a start. But the hair was pretty good. And no muscles.
And Una Salus did make me think "Oh... my... Dylan/Tyr fanfic could be... interesting."
Back to B7 wannabes in general, one thing that interests me is their solutions to crew numbers. I seem to remember that one reason why Gan was killed off was that they decided six (live) crew members were too many to handle in an average plot, so five plus two AIs was the best solution.
Andromeda's characters map very obviously on to B7's first-season crew, but they failed to understand about the numbers problem, as giving the AI an android avatar means seven humanoid(ish) crew. The result is that in a lot of episodes one or two characters get the week off, which is sometimes explained within the plot and sometimes not.
Farscape started off with four humanoids plus Pilot and Rygel, who I suppose could be regarded as Zen and Orac equivalents (one's helpful and bonded with the ship, one's portable, annoying and has a massive superiority complex). I'm discounting Moya as a character, though one could argue that she is, and that they therefore started with seven. Ignoring Moya, though, the arrival of Chiana brought them up to five humanoids plus two, the B7 solution. But since then they've added two more humanoids and lost only one, and Crais has effectively joined the gang. The result is that in mid third season, which is where I'm at, they've had to split the crew between two ships who get alternate episodes.
And Lexx solved it by a drastic pruning to three humanoids plus one robot head, with occasional fellow passengers (I suppose Lyekka was the longest-running of these), so doesn't encounter the numbers problem at all.
