The curse of sci-fi, it's reasonably expensive in relation to the figures it gets. SAAB had a huge budget for it's day and just couldn't justify it for the audience it got. Classic BSG suffered from the same problem, Bab 5 and New BSG had the advantage of cheap and effective CGI which meant they survived. By contrast a comedy series like 'Friends' has no stunts, no special effects, can be filmed entirely in the studio and get good ratings, the most expensive thing is the cast's salary. Then of course in reality TV you don't even need that
What kills me is, I hated
Friends, and I remember when some of the cast (or maybe all of them) were jockeying for seven figs and I thought: "These people want to get paid a million dollars each to act in this shit?"
I like Friends and to be fair the actors were worth it (except Ross?). But it's cheap to make, no expensive costumes or fancy SFX makeup etc so they can afford to pay the cast, no sci-fi show could ever pay it's stars that much
