Every TV series, even the great ones like Farscape has some below standard episodes. The thing is, this can be damaging when those episodes are at the start or end of a season. If it is in the middle, as a filler episode, absolutely fine, as I said, hardly any TV series go without them, but so far the first two episodes of Season 4, particularly after the best Farscape season for me, 3, are mediocre. Granny (Noranti) is annoying and does not make much sense, nothing really is explained, Grayza is not a very interesting villain, and there were only a few redeeming scenes in an entirely forgettable episode probably the worst one for me in now more than 3 seasons. Hopefully it picks up, I have watched Farscape as a kid, and now rewatching every episode as an adult, first 3 seasons are amazing, particularly 2 and 3, but 4 seems like it is going to be the least impressive of them all. Hopefully it picks up soon!
