Not to really get into it, but IIRC BSG's ratings aren't any better than Farscape's were (solid first 2 seasons, then a downslide). Neither one is really approachable to newcomers if they are watching an episode after Season 2. While both shows got more serialized, Farscape has plenty of standalone episodes that were very solid.....OTOH BSG's standalones are downright terrible -- the Starbuck/Apollo boxing match lovefest....the labor dispute in the mining division....uggggh. At the same time, I still tend to feel like FS's "mythology" episodes were still more approachable than BSG's. All you really had to know for later FS was that Scorpius had a mental clone inside John's head and that clone wanted wormhole information. For BSG, you can't really afford to miss an episode and it's more difficult to keep up. And let's be honest -- if BSG hasn't broken into "mainstream" appeal by now, neither show is going to.The Storyteller said:BSG may be highly serialized but its Sci-Fi flagship show, its won Emmy's and its acclaimed as on of the best dramas on TV. A large chunk of the fans are people who dont usually watch Sci-Fi and they love it because it doesn't have too much of that (which is probably why a lot of people were turned off by season 3's direction).
Farscape won a couple Hugos, and had heavy accolades from the likes of TV Guide but couldn't really retain its numbers with the retarded ways SciFi went about airing it. (Not to say that TV Guide is a big important critic, but it represents the mainstream pretty well). What Emmys did BSG win? I don't recall that happening, but I don't keep up with awards...
At the end of the day though, BSG is pretty much getting the Farscape treatment. SciFi doesn't want more than 4 seasons, they just want enough to push into healthy syndication territory. FS got similarly insulting renewal offers after Season 4 where they only wanted to commit to a half season (the producers refused....something I have a hard time forgiving them for). Farscape was a flagship show, much like BSG.....but for whatever reason SciFi just doesn't care about that sort of thing. If a show is a money-loser they look to drop it, no matter how much prestige and attention it brings the network.
If they dump BSG, it will probably get the same deal as Farscape -- some 4 hour miniseries to tie things up in a fairly hasty and unsatisfying way. I doubt they'll let it go "unfinished".....but if you think they are gonna pony up for the remaining 8-12 episodes I would not be so certain.
