Eh, I thought the fights in this last episode were underwhelming. The corabat that took place in the previous two episodes, and even battles that took place before (going all the way back to season 1) were much better. In comparison, this just looked like Celestial Being was cleaning up the leftovers and taking out the trash. Also, it was really surprising to see the end credits, the whole time through, I kept thinking that they would suddenly speed up. As for the season as a whole, it was an enjoyable watch, with minor bumps here and there (wasn't thrilled about the lack of development certain characters got later in the season). Had a nice ending, if a bit lackluster. Though, I did like Saji's point about being ignorant to the world's problems.
Useless Character Award goes to: Marina. She's been completely useless ever since her appearance in the second season, doing nothing but getting jailed, hiding in rooms, worrying instead of doing anything, putting down people for actually getting stuff done, refusing to protect the children, and in return, people still look up to her? Yeah, she wrote a song, whoop-dee-doo. I know she has her beliefs in how to achieve peace, but I think the writers screwed up bad in how to display them.
