The Wheel of Time; Endless, almost literally

[Luckheart]

My brother has read The Wheel of Time series once, and has been in the process of re-reading it for about a year It's worth mentioning that its like 13/14 big books long, currently, and the first author sadly passed away and it has been continued by another.
He has often tried to get me into it, and I did consent once; yet I only made it to the fourth book, which seemed to drag on a bit - He said it picks up, but I think he may be lost in the skill-river when speaking of this series hahaha

So, my question is; Who has read a sizeable amount of this series, or even finished it? (I'm fairly sure the last book came out recently, although it may have just been the most recent).

If anyone fits that criteria, I'd be keen to discuss the series (keep in mind I'm only up to book 4), and please advise me whether it'd be worth the mammoth effort !

thanks!
