How on earth...? What do they spend it on? There's been very little location shooting, no extensive CGI. It's mind boggling.
No, it's not mind boggling at all The West Wing could spend some 6 million per ep. without aliens, stargates and much location shooting.
Um...they had a very, very expensive (And large) cast. Expensive guest stars. Expensive location shooting in Washington, DC (for an LA-based show, which in turn is more expensive). The West Wing had great production values, and a pricey cast, it's not hard to see where the money went.
Stargate Universe has a cast mostly of unknowns, and for the most part has been shooting on their standing sets (in cheap Vancouver!) for the past five shows. And with one (count 'em, one) alien appearance so far...I'm still waiting to see where all the money goes.
The two biggest stars of The West Wing were Martin Sheen and Rob Lowe and Lowe left the show because he wasn't making the same amount as Sheen, other than those two the large cast were largely unknown as well. And Stargate Universe has already filmed in New Mexico and they've gone back to Las Vegas as well. And they use more CGI than most shows do.
Still there's alot of non sci-fi shows that cost alot more than many sci-fi shows do. Still a series shot in HD can't be cheap after they match up all the visual effects, the launch of the shuttle is a good example.
