Mixed bag response .. I was an avid reader in high school (late 80s), but there was a lot of garbage and quality books I was forced to read. I don't recall hating Of Mice and Men, and the Pearl was depressing as fuck, but I didn't hate it. What I did hate was the Great Gatsby and The Scarlet Letter. Both are atrocious American literature. My wife, ten years younger, loves the Great Gatsby. It could be the fact that I had to read it through the whole symbolism lens, which ruined any potential enjoyment of it. Another book I had to read was To Kill A Mockingbird, and I absolutely love that book, as well.
While the whole time my preference was Science Fiction and Fantasy. I read through LoTR by the time I was 15, dove into a bunch of fluff Anthony's Xanth books, which I realize are just total fluff, but his Incarnations series was good.. I think? And then of course I got into "harder science" and reading, like Asimov and Herbert as I got older and into my late teens/early 20s.
I tend to agree that if give kids a chance to pick what they want to read, they'll find it far more interesting. Granted, I probably wouldn't have ever read To Kill a Mockingbird on my own, so there is something to be said about that, as well.
