If you are a big fan of fantasy books, then they are a must read. Its one of the preeminent series of the genre, and justifiably so. However as
@Stupendous Yappi pointed out, it can get to be a bit of a slog. Books 1-6 are really good. Then books 7-10 bog down. The author created too many side character and side plot points, then he didn't know how to wrap them all up. He also has a bad habit of going into too much detail on minutia (you will read more about the flavor of various teas than you ever cared to). So the books just keep bloating. There are some definite high points in that middle section, but overall the quality takes a noticeable dip. Just be prepared for the slog and realize its ok to skim over the more mundane bits of those books. The author Jordan, started to right the ship with book 11 thankfully. Unfortunately he passed away before he could finish it. The last 3 books were written by a different author, Brandon Sanderson. Sanderson has become my favorite author, because I felt he did such a good job wrapping up the series. And because his own stuff is really good. So Books 11-14 go back to being stellar, making the whole thing IMHO worth reading.
Yappi also recommended Joe Abercrombie, who is very good. Abercrombie writes more grim dark fantasy where there is no real hero, everyone is just varying shades of bad. Wheel of time is more classic fantasy of light vs darkness with the farm boy fated to save the world from the big evil.
Amazon is making a Wheel of Time series, if you would just rather watch it then read it as well. Its currently in production and should release to Prime this year or next.
