Dr. Who - 2nd, 3rd, and current Dr.

Battle Star Galatica - current version

Star Gate Atlantis

UFO

Babylon 5

I could probably add more but this is my top 10.

I love Futurama, too. Didn't think to put the Avengers in this category, but agree that it, too, is good.

Top of the list is Battlestar Gallactica (new series)... in fact they go on the list of my all-time greatest TV shows. I was also quite addicted to Star Trek: The Next Generation. Patrick Stewart... best captain ever.

But do you guys remember that show "V" (http://en.wikipedia.org/wiki/V_(TV_series) )? Holy cow, that scene where Diana (that leader lady) rips off her face is STILL one of my favorite TV moments ever.

OK, my top 10:

Battlestar Galactica, the new series

* Firefly * egads, can't believe I forgot this!

Star Trek, DS9

Star Trek, TNG

Babylon 5

Star Trek, Original

Star Trek, Enterprise

Samurai Champloo

Cowboy Bebop

Red Dwarf
