Perhaps I went into this series with unrealistic expectations but I found it pretty disappointing. Same for Rothfuss. There is a huge volume of older fantasy novels that are a much better investment of time, IMO.
Probably fair to note that Sanderson wrote a bunch of those books to finish up the series after the author died and at his estates request?
I liked the first Mistborn trilogy, but couldn’t get into the later ones.
For recent large scale fiction that’s also not going to work for everyone, I really liked the Terra Ignota series. (But, if the warnings and the first chapter put you off, you’re not going to like it)
IIRC Sanderson has stated that he's trying to set up a Star Trek type setting. He's developing all these different cultures with different values, and eventually they're going to become space-faring and come into conflict with each other over their different priorities.
TWoK reminds me of the (Mirror-Moon TL of the) original F/SN VN in that the author/TL being bad at realistic characterization actually enhances the experience. F/SN Shirou and TWoK Kaladin are both weird broken robots with warped perspectives, and exposing the reader to an exhaustive amount of the (creative and surprisingly involved) setting, both mundane and horrific, through those perspectives is actually pretty interesting in a literary way and ascends above what could otherwise have been just plain bad writing.
Other posts in this thread have referenced the development of Kaladin's character through the arc of the plot, and I think that's what lost me. "Fixed" Kaladin is an uncanny-valley imitation of a fleshed-out character; "broken" Kaladin is, intentionally or unintentionally, a lot more fun. I found myself actively disliking many of Sanderson's attempts at expanding his characterization, especially in RoW.
