We’ve enjoyed Syfy’s Battlestar Galactica, Caprica, Eureka, Haven, and Warehouse 13.
i too enjoy eurek, wharhouse 13, and haven. eureka is just fun and i like the characters in haven. i sometimes think people, myself included, can read too much into some things like looking for an agenda in every episode of every tv show. i watch shows to enjoy some mindless fun and watch how the characters develop and interact. if i want to stare at a screen and really think, i play computer wargames or climb into an alternate universe with stargate, babylon 5, or farscape on dvd.
i also watch bones, big bang theory, ncis, castle and just got into burn notice which, again, is about the character interaction.
