Judging from these comments and the initial rating, looks like Syfy might have them another 'Eureka' on their hands; that is, a modest success. A little too silly, a bit too light & fluffy for me (as is 'Eureka'). I won't be back. But I will give the new Stargate franchise a look, as it's rumored to be darker than it's formulistic predecessors. I do love me some dark.
And, of course, 'Caprica' will be must-see-stuff. The pilot was very encouraging, IMO. So, I won't be completely abandoning the channel but can't see myself dropping in very often, as has been the case for the last half-dozen years. Rebranding? Meh. "Serious" sci-fi is still a rare thing on Syfy, and apparently will be for some time to come.
