Smallville

Sliders
Heroes
Fringe
Haven

In no order:

Star Trek: TNG

Star Trek: DS9

Stargate SG1

Firefly

Warehouse 13

Quantum Leap

Torchwood

Edit: Sliders (I knew I was forgetting something)

Edit: Surface

Edit: Falling Skies

I know there are a few others that escape me ATM.

(I personally consider superheroes as a separate deal, even though they technically are a sub-genre)

Sci-Fi shows, huh? Ok, here we go (inpo):

Star Trek (TOS, NextGen, DS9)
Doctor Who
Firefly
Fringe
Sliders
Early Edition
Twilight Zone
Quantum Leap
Amazing Stories
Outer Limits
Battlestar Galactica (both versions)
Babylon 5
V (again, both versions)
Alien Nation
Stargate SG1 (never saw Atlantis, but it's on my To-Watch list)

That's about it - off the top of my head anyway. And if comedies count, then this list will get a lot bigger. Same with including comic book/superhero-related series.

Same here. But considering how many superhero films are out there now, I'd almost say they could almost have their own genre. Maybe "Comic Book Movie" is a better descriptor for something like that.

The Adventures of Brisco County Jr.

Quantum Leap
Fringe
Star Trek TNG
Dr Who
Warehouse 13
Alphas
SW Clone Wars
X-Files
LOST

Twilight Zone (60s one)
Battlestar Galactica (70s one)
Firefly
The Clone Wars Animated

There are so many but these are definitely up there.

Stargate SG-1/Atlantis
Star Trek: TNG, DS9, Voyager to a lesser extent
BSG (2000's)
Farscape (never gets enough love)
Futurama (can we count that one?)
Firefly
Warehouse 13
Sliders was good back in the day.


There are others that aren't coming to mind. Also, despite what the SyFy channel wants us to believe, I consider Science Fiction most separated from Fantasy and Superheros (depending on the setting).

Star Trek TOS, TNG, Voyager
Firefly
Stargate (SG1 and Atlantis)
Battlestar Galactica (both)
Smallville
V (the new one. Not seen the old one)

There are so many good ones! My tops one are:

Stargate SG1/Atlantis

Start Trek the Next Geneartion
Start Trek Deep Space Nine
The X files

I know there are loads more that I just can't think of right now.
