I've just finished watching the 4th season of Farscape and I ask, why was it cancelled? What were Sci-Fi on? This was ana amzing show. All we get to wrap up the series is a mini-series, which is cool, but I did hear the plan was that they makers were looking to make it a 5 year series. The show worked so well and it seemed like they had a great plan for it as each year something new developed and storylines spread over multiple episodes. the characters had character! man! So gutted it got the axe. I'm looking forward to the Mini though. But I think anyone who liked it would have preferred another 22 episodes.
Anyone who has not seen it just for the reason, "They never got around to it" like me, then I suggest you go check it out.
