YMMV. I'm a big Hesse fan, and I tried reading The Glass Bead Game twice; couldn't get past 30-40% of it in either try, it was just too boring.
I'm a sucker for slow burns in cinematography and books, but you can't just have no pace or structure and then say "yeah, these kids have no patience".
My completely uneducated opinion of the glass bead game was that Hesse was describing what could be a very interesting concept in a very poor manner, always high-level, and abstract enough that at times I thought he didn't flesh it out in his mind either and couldn't convey it properly.
