What Is The Best Sci-Fi TV Series Ever?

Blake’s 7

Where is twin peaks? That’s my vote

It was a tough choice between Doctor Who and Firefly, but Doctor Who won. GERONIMOOOOOOOOO!

Outer Limits
Max Headroom

You missed the X-files, how could you! It trumps any of these shows easily.

Red Dwarf
Twilight Zone
Outer Limits

The Prisoner pls.

Just some quick ones that come to mind, which were all popular during their times, are:

Aeon Flux
Lost in Space
Mystery Science Theatre 3000
Reboot
Space 1999
Max Headroom
SeaQuest
The Hulk
Quantom Leap
Buffy the Vampire Slayer
Futurama
The Jetsons
Mork and Mindy
Alf
Thunderbirds

Really? 13 episodes makes it the best series ever?!?! Have you even watch any of the others? Frankly, there are at least a half dozen that are better than Firefly.

The X Files ever!

BattleStar is not propper scifi, its fantasy in a futurist setting.

Not necessarily the best, but some that have not been mentioned that may be missed by many:
ALF
Alien Nation
Amazing Stories
Buck Rogers in the 25th Century
Dead Zone
Knight Rider
The Lone Gunmen
My Favorite Martian
The Pretender
Seven Days
The Six Million Dollar Man
Smallville
Star Wars: The Clone Wars
3rd Rock from the Sun
Voyagers!
Warehouse 13

X-FILES. The best then. The best now.
That. Is. All. Earthlings.
