We once read a book called "Feed" in high school - a ham fisted anti-capitalist book. Wherein citizens are 100% connected to an internet like service that only exists to sell them products. 90% of the class couldnt get it. Even when the teacher sat down and explained the entire plot of the book they still couldnt wrap their head around it.
Belgariad/Mallorean is like a 7/10 imo but I haven't read it since high school maybe, I definitely have always thought the Riftwar Saga, Xanth, Recluce was better though. Funnily enough though, aforementioned comrade was the one who put me onto both Xanth and Belgariad. We both have/had a big love for fantasy magic lol.
