Both Farscape and Lexx rocked more than Star Trek Voyager.
Seriously, Lexx was good but the satirical fourth season was more enjoyable if you're Canadian (as the general American doesn't give a fuck about the ATF). Lexx worked better in a weird universe (or two), not when it was dealing with Earth and such.
Farscape, however, was getting a little better....but truth be told I stopped watching long before it got the axe by Sci-Fi. At least Lexx decided when to end, Farscape just got a bat upside the head. Still, hope they continue somehow.
