I know wacky already did this, but it deserves a second look.
25. Dark Shadows (1966-71) - eh!? Wha...?
24. Smallville (2001-now) - Are you kidding me? I know there aren't a lot of shows to choose from, but really? Why not pick the original Superman TV show? THAT WAS FUCKING ORIGINAL!
23. Red Dwarf (1988-99, 2009) - Hold on... A comedy show where they barely show any real sci-fi stuff? How is this on the list and SG1 (which actually developed a far greater plot and sci-fi material) isn't?
22. Incredible Hulk (1978-82) - Yeah, I can see that.
21. Night Gallery (1970-73) - Where do they come up with this shit?
20. Supernatural (2005-now) - Don't watch it. I have a great feeling that it's totally ghey.
19. Highlander: The Series (1992-98) - Needs a higher ranking.
18. Babylon 5 (1994-99) - Needs a MUCH higher ranking.
17. The Outer Limits (1963-65) - Needs a higher ranking.
16. Quantum Leap (1989-93) - Needs a higher ranking.
15. The Dead Zone (2002-07) - OMG REALLY!?!?!?
14. Angel (1999-04) - The first signs that the people who made this list are totally incompetent. How does this beat out B5, Highlander, Quantum Leap, DS9, AND Sg1!? It was a fucking spinoff of a mediocre-at-best TV show. AND WHERE THE FUCK IS CHARMED!?!?!?
13. The Prisoner (1967-68) - Again with the obscure short-lived crap...
12. The 4400 (2004-07) - OK, no. This show didn't deserve to even be on this list at all and they put it at 12!? Fags...
11. Firefly (2002-03) - Yes. A fantastic show.
10. V (miniseries-1983) - See comment for 13.
9. Jeckyll (2007) - Who?
8. The X-Files (1993-02) - Totally deserves a top 10 spot.
7. Star Trek (1966-69) - Again, a show that needs to be in the top ten.
6. Lost (2004-now) - What wacky said. though, it doesn't beat TOS imho.
5. Battlestar Galactica (2004-09) - Never watched it, but the feel around here tells me that it's somewhat deserving.
4. Buffy The Vampire Slayer (1997-03) - [CAPSLOCK]HOLY BALLSACKS!!! HOW THE MOTHER FUCK DID THIS SHOW BEAT A DOZEN OTHER SHOWS THAT ARE MORE DESERVING OF BEING ON THIS LIST!?!?!? NOT TO DIS TISIPHONE OR ANYTHING, BUT THIS SHOW WASN'T ALL THAT WONDERFUL. AND AS TIS SAID IT'S ONLY A FANTASY SHOW, NOT SCI-FI!!!!![/CAPSLOCK]
3. Star Trek: The Next Generation (1987-94) - It's not number 1?
2. The Twighlight Zone (1959-64) - Yes. Deserves it's post.
1. Doctor Who (1963-89, 2005-now) - You're kidding, right? right? please tell me you're kidding.
Shows that were left off the list that should have been there if the creators of this weren't teenaged fangirls: DS9, sg1, Charmed, Xena, and Hercules.
