I'm not a big fan of Battlestar Galactica - Star Trek claimed to be Space Opera, to get past the networks that thought intellectual Sci-Fi was a losing proposition. BSG was, in fact, Space Opera - Good Space Opera, but space Opera.
I don't think it's going to be all that good - first glance appraisal is that it's far to close to the same BS that's been served up before. On the other hand, the last time I just decided I wasn't going to watch a show was when Dark Angel got replaced by Firefly, which turned out to be a good show, with good writing, and I rather wish I had had the chance to see it all the way through. My ability to judge a show in advance of actually watching it is demonstrably fallible.
Perhaps no one else here possesses that particular flaw.
