B5- Great storytelling, lots of aliens and political intrigue and it shows a realistic universe in which all races are out for there own competitive advantage....unfortunately the spin offs and made for tv movies were just bad and casted a dark shadow on this show.
Star trek (all series) I loved the story telling but the series drifted away from its conservative cold war influence stories, original star trek, to the "we should all love each other" utopia stories, Enterprise..Seriously they need to burn all evidence that the Enterprise series even existed....one last thing...Captain Kirk is the "Man" and Picard IS NOT.
Firefly- WOOT space cowboys...the characters make this series awesome, if you don't know what this is then go to Netflix and stream the series and the movie "Serenity". This is easily the best Sci-Fi show that got canned too early.
Farscape - out of the major series, I think Farscape is the most creative in creating alien characters and landscapes, but I think what put people off of the show was that it was a significantly dark bit of story telling..l The lack of hope and irrelevant funny moments by the main characters is what killed this show.
Stargate Sg-1 - Colonel O'Neill, Major carter, Daniel and Tielk are all that matter in this series and makes it great...the stories are fun and always have a hint of conspiracy in them. Anything else with the stargate moniker can just be thrown into the trash.
Star Wars- stories had no depth at all but it was fun and flashy, except for ESB, the story in that one was awesome probably because George didn't direct it. I loved and dreamed of being Luke as a kid but when Lucas started to remake them in '96, the magic just dwindled away as soon as I saw that he changed "the Han solo shot first" scene. They should make a law that film maker can't change their films once they arrive at the theaters.
Dr. Who- my introduction to Sci-Fi as a kid was Tom Baker as Dr. Who and I love watching it..The stories are character driven with suspense as the primary literary tool and not action. Some people think it is too fantastical and depending on the charisma of the person playing the doctor the series is either really good or very bad.
Lexx- Easily the craziest friggin Sci Fi show ever, but it's very addictive to watch. Lexx is very hard to describe fairly...the easiest breakdown is to say that its a group of misfits escaping bad guys and flying through the 2 universes inside of a bug the size of Manhattan.
Battlestar Galactica- out of the major series this is my least favorite but I know a lot of folks that absolutely love it. I actually enjoyed the original and the 1980 series (even though you can see the strings on the ships) but the newest incarnation was very soap operie with producers of the show trying to entice more women to watch it, everyone has a secret dark past and I just didn't it enjoy much
There are lots of other space based Sci-Fi series out there that I didn't mention because I didn't think they were either relevant enough or they, I just didn't care for them or they were Anime' . Don't get me wrong there are some great anile like cowboy bebop and robotech but Anime is filled with tons of different space based series and I wanted to stick with live action series.
