I think Farscape is awesome. I never compare it to other things because I consider it unique.
I've seen Farscape described the way Neroon
just did too many times. "It's Star Trek for the 90's (or 2000s)!", "It's a grown up Star Trek!" blah blah blah.
Star Trek was Star Trek for the 90's and the 2000's and if you want "grown up" Star Trek then watch Deep Space 9.
