I enjoyed Through the Looking Glass
a lot. Again, it's the sort of thing that could have been done on Trek, but by this stage Farscape was just doing it better and more imaginitively.
A Bugs Life
was decent, but not as good as the last few episodes.
The real story though, is Nerve/The Hidden Memory
which are just fantastic. The episodes really show the series exploiting its full potential and I think this is the best stuff we've seen so far on Farscape. No fat, just great storytelling and the stuff about Moya's baby is the icing on the cake.
Bone to Be Wild
is OK, but it feels a bit odd to suddenly have the ongoing story arc relegated to B-plot in favour of aliens of the week like this.
