I'm a ST fan and I would put my favs as this: TNG, DS9, TOS, ENT and VOY. I haven't watched BSG but I'll do it when the entire series is on DVD. A friend had pushed me to watch "Firefly" and the movie: "Serenity." I actually watched the movie first, then the series. I was really pleased with both. I loved the writing in the show. I really enjoyed the characters. In the various Trek shows it seemed to take a couple of seasons for the characters to be fleshed out. In "Firefly" it seemed to happen really quick. The good/bad thing about it for you would be is that there's only 12 or 13 episodes so it wouldn't be a huge investment in your time to watch. When all was done, I was glad that I watched.
