Top 50 SciFi shows
Boston globe posts a list of what they think are the best scifi shows to hit TV.
6) Stargate SG1 - my favorite show of all time, and perhaps the longest running recent scifi? I don't count Dr. Who in this (which is #7 btw).
5) Babylon 5 - an excellent show, but one you really need all 4 seasons of; almost every episode is involved in the story arch. The 5th season was a filler joke.
4) X-Files. Also a great show. My wife is addicted. Err, was. She's now a Josh Weldon fangirl.
3) ST: The Next Generation. My 2nd favorite show of all time. Also ran a long time, had 2 movies, very successful franchise.
2) Battlestar Galactica (the new 2005 series). I disagree with this, putting it above shows that ran for 10 seasons (SG1), multiple movies (B5, TNG), etc. And the first seasoon was not spectacular I think. The miniseries was great (eps 1 and 2?). 2nd season is much better. Again, one of those 'must see every show'. Time will tell with this one.
1) ST: Original Series Well, this is really the granddad of them all. I thought it was hoakey, but that's more of a generational thing I guess.
Not in the top 10:
Andromeda (Gene Roddenberry); a great show, esp the first two seasons. The last season completely sucked, as did the finale. I would list this as #5.
Farscape; probably the series that made the SciFi channel (that and MST3K). Similiar to B5 in the 'must see every episode'. Big story archs, a very fun show if you see every episode. Otherwise you won't get it. I'd rank this as #4.
SG: Atlantis. From what i've seen of this show, I like it, but i have too much in my life to watch it right now.
Also apparently Firefly, Buffy, and Angel aren't considered Scifi, or at least not the top 10. Buffy was good I guess, should be in the top 10 somewhere.
My ranking would be:
1) Stargate SG1
2) ST: TNG
3) Babylon 5
4) Farscape
5) Andromeda
6) X-files
Update: Firefly is #17. ST: Voyager is #14 (which is also a really good series, I think). Xena is #12 (this is fantasy, not scifi). Buffy/Angel aren't in the top 20, but Xena is? Whacky.

#1, ST, original series
#2, ST:TNG
#3, undecided...between X-Files (which had a good variety and was long running)...and Battlestar Galactica..(which has been good so far, but has only begun).
#4, Firefly.. perhaps. That one also has only begun.
