Not watching a program because it might not garner sufficient viewership is a self-fulfilling prophecy. Dumping a season's recorded but unwatched episodes, or even half a season's worth is crazy.
Well, yes and no. We're not a Nielsen household and record everything for later viewing. So what we do is irrelevant to the survival of a show. And we belong to an irrelevant demo for live viewer statistics anyway. I've gotten pretty philosophical about the cancellation cycle and practical about recording new shows.
I've recorded most new drama shows this year, watched the first episode, and in some cases then moved the rest of the season to date to an external hard drive.
I judged "666" as a likely ratings disaster. So now I can dump the recordings. No loss. My wife liked "Last Resort", so we've been watching it partly because after watching the first episode I figured it should be a 13 episode show - it should be properly wrapped up in the last two episodes.
During the debate and baseball playoff/series period, we did get caught up on "Chicago Fire." The other two I've gambled on by watching some episodes are "The Mob Doctor" and "Elementary." I liked Jordana Spiro in "My Boys" and she's again proving to be a talented actor in "The Mob Doctor" which may or may not make it on Fox. "Elementary" is quirky enough to make it and is fun to watch. CBS is promoting it.
"Vegas" I wasn't sure about so it's all on the EHD along with "Revolution." If indications are they'll be picked up, we may watch them during the holiday rerun season. Or not. There's so much to watch anyway.
