I did quite enjoy the first season, there was progression development of characters and lead-up for his eventual reunification with those that had transferred with him.
This series resolves all questions, but by the end of it I felt as if the mystery might have been way better than the resolution. I have to categorize this season it would be:
Filler episodes and parody, side-characters are main characters and put everything else on ice (also lets return them to a high-school b/c why not, every fantasy realm has them)
