It was sad that the first episode I ever saw of it was that freaky one where some sort of dimension warp created three Johns--one normal, one primitive, and one super-intelligent. In hindsight it wasn't that bad of an episode, but when I first saw it, it seemed so cheesy.
What I appreciate most about Farscape, which you rarely see in Trek, is that character motivations carry over more clearly, and the events of one episode can clearly affect someone in a later episode. John will recall when, three episodes earlier, he offended someone on the ship, and his current actions will be affected by that. Recovery from problems is never easy, but the stories are usually quite uplifting and optimistic.
Compare that to a Voyager episode I saw a couple weeks back. Good premise--Tuvok is mind-melding with folks but doesn't remember that he does it, and when he finally announces the command word to those he has melded with, they begin trying to take over the ship. It turns out that it was only the Maquis who were doing this, and Tuvok was calling up their old "I hate the Federation" instincts. It was a great episode, but then at the end they just wrapped everything up, with Tuvok melding everyone back to the way they had been before. No one even felt the slightest repercussion of "Hey, for a while, I _did_ hate the Federation, and it made sense." It was always too clean for my tastes.
Farscape has much better storytelling and characterization, in my opinion. Great show. Watch it from the start, if possible.
