/Thinks it was interesting that when ratings were good it was a sign of how great BSG is...when they are in the toilet...they're meaningless.
I don't think anyone here was using the good ratings of a sign of how good the show was. I certainly can't remember any such statements.
I think what's more important to people is if their favorite show will continue or not. That was important before it was decided this season would be the last. Now that it's clear that it is and it seems like they're really pulling this true, they are, indeed, truly meaningless for people following the show.
I think it's interesting that people who don't like the show keep pulling out the ratings as alleged evidence of a drop in quality.
