This season ended pretty strong, and dark.
The beginning of the season was kind of all over the place with no real story arc. Lots of the episodes were very fluffy and kid oriented.
By the end of the season stuff was coherent with most of the shows being roughly tied together in to a common plot with some side adventures mixed in that generally added to the overall character development. Some of the episodes were pretty dark too.
I'm hopeful we get more of the later - coherent, story arcs, and character development in next year's season. They can skip all the random kid oriented filler as far as I'm concerned.
Overall though I wouldn't recommend this series to anyone other than hardcore Star Wars fans.
