I didn't really like it when it aired and avoided watching it for many years. Never was a fan if the BSG/Lost show format with constant drama and flashbacks. The episodic style of SG1 and Atlantis, that's my groove.
But I watched it all the way recently and honestly grew on me. Still not a fan of all the filler drama and style of plot, but it has its good moments. And there's some decent acting in there. Definitely worth a watch.
