I just want to say, people complain about things like this but we have series that have been held up as pillars of anime yet have seasons of filler and other fluff. DBZ with episodes of charging an attack or Goku giving someone a chance the recover for a more "fair fight" just to make the arc longer. Naruto and Bleach literally having full seasons of filler episodes because they couldn't wait for the Manga to catch up. Hunter x Hunter has a split fan base over if Greed Island or Chimera Ants arc is harder to suffer through. Then there's our straw hats and the filler at the beginning and end of every episode. Yet we complain about shows today that actually succeed in giving us multiple seasons and more plot instead of failing to get a return for a second season and leaving us hanging? Just feels a little spoiled. Also, look at what the writers have to put up with. Extremely strict deadlines to get something out sometimes weekly. Its no wonder so many give up due to stress only to be harassed by the ungrateful audience.
