It's funny that you mention Wheel of Time because I'm on the Sanderson books now and I feel like everyone's personality changed due to his different writing style.

At first I didn't think Robert Jordan was a particularly masterful writer (at least not like Tolkien), but by now I have an appreciation for how each of his characters has a different personality which came through clearly in not only the dialogue and the character's actions but also the narration depending on whose perspective the chapter is told from.

But Sanderson though, it's like whoever the chapter's POV is from, it's all narrated in the same writing style. It loses a lot of depth and just feels kinda flat.

The dialogue is more bland too, and suddenly everyone seems just mildly autistic. It doesn't feel organic. And all their personalities are the same now. Like there's not much distinguishing one person from another anymore.

I'm still gonna finish the series now because I'm emotionally invested in it and want to see how the story concludes. There are a lot of plot arcs that really started to come together in Book 11 to set the stage for Tarmon Gai'don. I can't just put the series down. But my imagination needs to do a lot more work to keep the characters true to themselves.

There are still some chapters that I feel like Robert Jordan wrote before he died. Where suddenly the characters come to life again and the narration is told with more depth. Hopefully that lasts, cause those chapters are still nice.

But also, he left detailed notes of how to finish the story, and Sanderson interviewed his friends and family to better understand his intentions. So at least the plotlines will conclude true to the original author's vision.

And then there's the prequel which I'm looking forward to. That one was written by Jordan.
