Star Wars Rebels has been really good, but I fear for the pacing of the upcoming episodes. So far we know that the series will be 16 episodes in the first season so the break down seems to be.
the pre-releases shorts - one episode
spark of rebellion- two episodes
rest of the series is 13.
Now having thirteen episodes isn't a bad thing, but only being Half an hour really hurts some of the pacing problems, especially when two of the already released seven are arguably filler.
Now with that said tonight's episode Empire Day was actually really well done, though. Will be intresting to see if the speculation is true for upcoming plot points. Ezra's dad is Rex from the Clone War, and Fulcrum is Ashoka Tano also of Clone Wars
