Star Trek will always be my favorite -- the entire franchise, including all the TV series. Yes, some are a lot better than others... ;-)

Currently, I'm really enjoying Eureka though I only get to watch it on Hulu so I'm way behind. I missed some early episodes.

Quantum Leap was terrific -- thanks for reminding me of that one. I need to track down some episodes to watch of that. Scott Bakula!

Quantum Leap is definitely a classic, but Star Trek (all versions) needs to get a mention and I have suddenly become enthralled with the X-Files look-alike Fringe. What is nice about Fringe is that it definitely has a theme overriding most episodes that drives the plot. In that respect it has a little in common with Quantum Leap. Each have become a big part of our common experience. Think about what we would be without these lines...

• Make it so - Star Trek The Next Generation
• Oh boy! - Quantum Leap
• More power! - Star Trek
• The truth is out there - X Files

Priceless!

Does V qualify as a "series" it was a little too long to be considered a mini-series but it only ran for one season...Another one hit wonder (and don't get me started on the remake) is Battlestar Galactica...thought they both deserved a mention.

Star Trek was awesome. I really wish they did some sort of TV remake of the original series. Star Wars is also awesome, but I don't really like the new animated series. I wish both of them went back to the classics, and I wish Gene Roddenberry was still alive to make awesome shows that nobody can replace.

1. ST Deep Space 9
2. Stargate Universe
3. Star Trek
4. Quantum Leap
5. Star Trek Voyager
6. Dr Who
7. Stargate Atlantis
8. ST The Next Generation
9. ST Enterprise
10. Stargate SG1

In my opinion, Time Trax is better than Quantum Leap. It's a shame more people haven't heard of it.

1. Star Trek - All versions.

2. Stargate - All versions.

The above two are so close I could have called them a tie.

Then there is these OLD favorites: The Invaders, The Time Tunnel, Lost in Space, Time Trax, Land of the Giants, Voyage to the Bottom of the Sea, Seaquest, and of course Battlestar Gallactica. And if you want to go WAY back, Supercar, Fireball Xl5, Stingray, Capt. Scarlett, that's if you like marionettes. Boy I am dating myself. Geesh.

1. Babylon 5 with the great Andreas Katsulas as "G'Kar" holding and binding the entire series together. The thoughtful writing and Andreas' acting skills shining through all that makeup spoke of the human and alien condition both.

2. Star Trek the Next Generation with Patrick Stewart as Capt. Picard. Another classically trained actor with a good supporting cast and very good writing.

3. The new Battlestar Galactica. Olmos and McDonnell supported by Helfer, Bamber, Park, Sackhoff and Callis made it happen. Writing was so-so.

Twilight Zone (original series)

X-Files (all seasons)

I love lots of sci-fi series, but Doctor Who has been and probably always will be my favorite.

Star Trek and Quantum Leap were pretty good for Johnny-come-lately programs! (To put that in perspective, Doctor Who first aired in November of '63 -- even the original Star Trek didn't get going until '66!)

As a kid, I loved the '70s versions of Battlestar Galactica and Buck Rogers. More recently, I enjoyed Journeyman and Jericho. I was getting into FlashForward, so I'm peeved that it was canceled without too much resolution of the overall story. In fact, because this seems to keep happening with network science fiction shows, I think I may stick to movies!

Oh! Everyone's raved about the newer Battlestar Galactica series, so I'm hoping to get them all and have a marathon viewing one of these days. I didn't want to catch it halfway through, so I avoided it while it was airing.

Without a doubt... Babylon 5. Scifi for Scifiers.

It got right to the Scifi without the Star Trek-esque layman's discussion before it.
