Which sci fi tv show did you prefer to watch?

Star Trek.

Edit- misread the question… of those two, Twilight Zone.
In general:
Firefly
Star Trek- original, TNG, DS9
Twilight Zone

Back in the day Star Trek and Battlestar Gallactica!

I liked Twilight Zone.
Firefly is my all-time favourite, though.

Time Tunnel. http://en.wikipedia.org/wiki/The_Time_Tunnel

It was only on a short time, but it was great.

MST3K

From those two choices I would choose Twilight Zone. My personal favorites were X-Files and Quantum Leap.

I was a big fan of both shows. Outer Limits was my favorite must-see show when I was 12–13 years old. My friends & I deconstructed every episode at length.

Now when I watch them, TZ episodes are (usually) taught dramas with good acting & writing, showcasing some of the best actors of their time. Outer Limits doesn’t hold up so well—cheap & cheesy special effects, dumb dialogue, etc. Which goes to show what poor taste I had as an adolescent.

Twilight Zone

Red Dwarf, never watched the two you provided.

The Twilight Zone. I remember them being similar but for some reason, Outer Limits scared me or provoked me a bit.

Of those two, The Twilight Zone.

My real favorites though are Babylon 5 and Firefly.
