Wow, what a shitty list on their part. Why was Lost on there at all?

Honestly, I have a problem with your list as well, : )

Dollhouse was cool, but it has some serious plot problems. First, I always felt like the dolls were so powerful that they really had to strain the story to make them not instantly solve any problem. Second, the person who turned out to be the owner or whatever seems really out of character and was some serious Deus ex Machina, imho.

Terminator was great when Summer Glau was a kick-ass robot. But, like half way through the series, she turned into a pussy River. I don't know why they did it, but I couldn't watch it after that.

Not familiar with DS9, but TNG, BSG, and Firefly are all awesome.

On a related note, have you heard of this: http://www.cnn.com/2011/SHOWBIZ/TV/02/18/firefly.returns.ew/index.html?hpt=C2

Oh, and the casting of Alpha was awful. I know Whedon likes to reuse actors, but come on.

Yeah. Everyone's blowing that out of proportion. Fillion has always said he'd drop anything to do Firefly. And there's almost no chance of FOX selling the rights.

But Dollhouse WAS awesome. Topher/Adelle is one of the best relationships in all of television, and the overall plot arc, especially season two, was epic.

What do you mean? The article says they already have the rights.

This list is garbage, I disagree with half of the placements and they forgot Sliders! How can you not have sliders in the top 10??

Really? Why do you say that (about Alpha)? I thought Tudyk did a pretty good job with the insanity angle.

Because, he didn't come off as dangerous-insane, he came off as silly-insane. I don't know of that's because of his acting, or my inability to get Wash out of my head, but either way, I could never take his character seriously and it made it really hard for me to understand why everyone was so worried about him.

To be clear, I loved the show and was sorry to see it go, but there's no way it should be at the top.

Dr. Who (all since 1963)
Star Trek (TOS)
Space Patrol
Fireball XL5
Thunderbirds
Space 1999 (first 2 series)
Babylon 5 (while Claudia Christian was in it)
Firefly
The Survivors
BSG (2004)

@ Abge:

They have the rights to air it, not produce new ones.

And he was supposed to be silly insane, to an extent.

Oh, I understand this, but it sounded like they were going to have cool interviews and stuff after each show. I've never expected them to actually make new episodes.

I can believe that Battlestar Galactica was number one. That series would be pretty closed to my favourite television ever. I didn't see it when it was on television, but rather I watched the box sets, and often several episodes in a single setting. The first couple of series especially, the drama, the suspense, the excitement, I could not stop watching.
I have heard great things about Firefly and I have watched a couple of downloaded episodee, but it hasn't yet grabbed me the same was as BSG.

FAIL AT #!! :O

Don't get me wrong, BG can have a spot in the Top 10...

BUT #1?!?!

NO!

There is no way BG beats out the original Star Trek AND The Twilight Zone AND Doctor who...even though the last one isn't one of my favorites per se, a Top 5 spot is still warranted.

Shame, since almost every other ranking I agreed with.

obiwanobiwan's FIXED Top 10.

10. Lost (I don't know if it's "sci-fi" so much as it is "adventure/survival," so a lower slot
9. Firefly
8. Lost In Space (Come on...no love for the campy classic? FORGET THE FILM!) :O
7. Babylon 5
6. The Hitchhiker's Guide To The Galaxy (Impossible, er, highly improbably this didn't get a slot!)
5. Star Trek: TNG (7 seasons, 4 films, the mainstream knows it, and PATRICK STEWART!)
4. The X-Files (I didn't like it, but for those who did, this is a classic, and also well-known)
3. The Twilight Zone ("A dimension not only of sight and sound but of MIND"...LEGENDARY)
2. Doctor Who (Longest-running, and second only to...)
1. Star Trek (Boldly going where no one with cardboard sets and actors with bad accents have gone before!)

:D

Really, The Twlight Zone, Doctor Who, and Star Trek can each be considered for a #1 tie, each one deserves it, it's a matter of taste...

The Twlight Zone had maybe the best ration of good-to-bad scripts and Rod Serling...
Doctor Who is longest-running...
And Star Trek is easily one of the best TV shows ever PERIOD, most Top 20 lists have it somewhere...

Rod Serling, The doctor, and Captain Kirk:

HOW ARE NONE OF THEM AT #!?!?!?!

(I say the Klingons and Daleks are responsible and have just crossed into the Twilight Zone to try and, you guessed, it, TAKE OVER THE WORLD!) :p
