Ahh... Wheel of time. It was one of my favorite book series as a child. But lets hope it does not end in the same way. When Robert Jordan wrote the Wheel of Time series he first imagined it as a trilogy of books depicting good battling evil. Literally Jesus vs the Devil. Eventually as he wrote he got better ideas and made the story more ambiguous with shades of gray. But unfortunately his new ideas did not fit in with his old ending. So by the time he had finished book 6 of 15 he had pretty much ran out of ideas and started to write filler books until he died after releasing book 12. He had hoped to be able to create a good ending, but that never happened.
Then came Brandon Sanderson and took over the series for the last three books. The first two he did really well. Because he got rid of the filler and seemingly got the plot back on track. Unfortunately the last book in the series; "A memory of light", is probably the worst book I have ever forced myself to read. Why? Because RJ never planned a new ending and Sanderson was forced to write one from the defunct notes from the beginning! Which meant that he had to retcon almost everything that happened before and... its the most stupid thing I've ever read!
Anyway, I wonder how far ahead SIU plans his stories and how much of his plan he changes? Because I feel that a lot of things about the story have changed since season one. I would call season one a seinen that was based around mysteries and people acting smart rather than fighting. Modern TOG is all shounen though with his ever expanding band of namakas that fight one on one battles with bigger explosions in every battle.
I also just remembered that in the first picture we got of Yama. (With him in the bath) he was missing one arm. But next we saw him he had his arm and Doom was instead missing an arm. I wonder when that change occurred and how big a part of the cage section was planned ahead instead of just writing it as he went along? It might be that SIU does not actually have that complicated plans made up for the future for another author to build upon. Just like with RJ.
