It depends on what you're looking for.

If you're happy with kind of shallow young adult fantasy vibes, go for it. The magic system / world-building / characters aren't especially fleshed out, but they get the job done. The plot again isn't especially noteworthy, but it was a pretty fun ride and easy to digest. Basically it's very accessible fantasy, but somewhat mediocre.

If you're really into classic high fantasy stuff, maybe give it a miss. It probably won't hit the spot for you.

Regardless of whether you read the books or not, just... forget about the movie.
