I've only read four of the fourteen books
yeah I also read the 3 or 4 (as a tween, so it's been a while) and that's a pretty good summation
not bad as far as Tolkien knockoffs go. or to be more accurate, a Tolkien knockoff crossed with some very thinly reworked elements from
Dune.
I gave up on it because it becomes increasingly unwieldy the further you go - he had a worse version of George R.R. Martin syndrome where you just keep adding characters and factions and settings and plot elements until the main story is buried under an avalanche of detritus and you're forever interrupting it to check in on what 50 mildly interesting side characters are up to. at a certain point as a reader you just think to yourself why am I grinding through all of this.
also everyone is always turning out to be someone else in disguise or possessing their body or actually a reincarnation of some ancient hero, no one remotely important ever actually dies despite everyone being super awesome at fighting, etc.
like Rich I'm making it sound terrible but it's not. the writing is a tier down from GRRM but that's still toward the higher end of genre fiction. it's all basically recycled but as Rich says enjoyably enough. it centralizes women which is a nice change from most fantasy.
