It's expensive, it's ratings tanked and it frankly wasn't all that good most of the season. Very up and down. It wasn't even going to get a full season pickup and would have been canceled last fall but Time Warner cut it's fee and wanted it to continue to hopefully build up hype for the movie (which of course has nothing to do with the TV series but I digress). Fox is starting to look at DVR viewers and online viewer but let's be honest, they don't care that much for them because what makes money is advertising and if people aren't seeing those ads then they don't make money so it doesn't matter if 10 million watch it via DVR, they aren't watching the ads and thus "don't count" in the antiquated way ratings are done. But Dollhouse got renewed based on being a lot less costly. SCC really can't cut it's budget all that much without people noticing. Dollhouse is more "procedural" similar to a CSI in terms of sets and not a lot of special effects. But it's strong DVR and online viewing did influence Fox as well so maybe they are starting to see the future and perhaps Dollhouse will be the first "experiment" in that way.
