@Ghost It's also not a consistent ride.
The first five books are (in my opinion, obviously) quite good. Not necessarily on the masterpiece level but great reads with a lot of ideas, fresh concepts and interesting characters.
For instance the way the One Power worked and the sheer level of detail RJ put into it were pretty amazing for the time, paving the way for Sanderson's own magic systems later on. A lot of details were also awesome inventions - how ta'veren worked, for instance, explained in an in-universe fashion why these characters always seemed to be around when interesting stuff... happened to happen or survived out of luck and circumstance. Those weren't just coincidences, it was because they were ta'veren.
But, again in my opinion, some time during/after book six things went wrong. Too many dangling subplots, and RJ kept opening new threads instead of closing older ones. We kept being introduced to new characters (each of whom seemed to be more powerful than the last, when we were already told the last ones were the most powerful seen in hundreds of years) and the bloat built up both in in-setting power but also just things that needed to be resolved and weren't being.
A TV show can fix some of those things, hopefully. If they are lucky enough the casting will work, too.
That's many ifs, but I'm hopeful. Now if we get a great WoT MUSH out of this, I'd be overjoyed.
