I'm not sure I agree with this. People are different and not everyone has to enjoy so-called literature that is not pure entertainment.

I have shelves full of books I had read before finishing school, and 90% of what we read in English lessons (I am German) was ok, and yet I hated 90% of what we read (or supposed to read) in our German lessons. Maybe it was the selection, maybe it was implicit bias (I also liked English lessons and my teachers, and didn't like either for German). Just some from memory (annotated Shakespeare was ok, I liked Poe, I liked Huxley)

So no, except for a few you would not manage to convince me to give them a second chance.

And also no for your last point, some Dan Brown novels were ok and I didn't enjoy the rest in the first place ;)
