My favorite television series is Battlestar Galactica on the Sci-Fi Channel. Here is a link to a clip from one of my favorite episodes. The first minute and a half is talky, with Commander Adama asking a captured human looking Cylon model why the Cylons hate the human race. Stick with it, because it is followed by one of the most awesome space battles ever. If you have never seen the new Battlestar Galactica, check this out and it might interest you in watching the show. If you are familiar with it, here's a chance to revisit a cool scene.
Incidentally, I don't know if you need a Youtube account, but I haven't figured out yet how to actually have the video appear on my blog instead of providing a link to the video.
Please note that the link above no longer works. Here is a new link containing a truncated version of the battle scene from the episode Resurrection Ship Part 2.
