Does "Land of the Giants" count? Loved that as a child. I was (and still am) a "Twilight Zone" (original series) nut, too. Until it got pulled
recently, I liked Weird Science, too.
Definitely old TZ was cool. I liked B-5 quite a bit and old Star Trek (New stuff was too wimpy for my taste) But wouldn't the X-Files count as sc-fi?
That's my favorite show period.
