I read the books and enjoyed them.
The show runners made a long series of horrible mistakes in making the TV Series. I watched the whole season 1 and was very disappointed. I get that they needed to compress 14 long books into something reasonable, so some plot "short cuts" would need to be made. But they destroyed some plot lines while making others up from whole cloth. Plus the casting choices were flatly abominable. Not specifically because the cast is diverse and inclusive, there are lots of different "races" in the books. But the main five characters in the books were all from the same small mountain village, isolated from the rest of the "world" for ages and ages and therefore were much alike. The show has them more diverse than any good sized modern city. As the books begin all five are acquainted and are teenagers, but none of them are romantically involved. The show is very different in this regard which ruins multiple plot lines from the books.
There is more, but you probably get the the gist. If you haven't read the books, it is probably a decent series, though much of the backstory of the various factions aren't well developed.
Just my $.02 and probably not worth it.
