I love reading. I've read all of A Song of Ice and Fire since christmas. Before that, since August 2010 I read about a dozen or more 40k omnibuses and the entire Horus Heresy series. I've read the Dark Tower and LotRs twice. I read a lot is what I'm saying.
But by god, some of the shit they make you read in school is fucking painful. First we have the obvious Shakespeare (I remember Othello and Twelfth Night), both of which have some of the twistier plots and might have been interesting if not for 2 things; 1) We had to stop every third line so the teacher could explain what the hell was going on, which leads directly into 2) They're written in an archaic form that is extremely hard to follow for a lot of people, especially teenagers. I say this as a guy who likes to read, and reads pretty well, but even I struggled, so I have no idea how everyone else fared, but either way, when you have to keep stopping and starting to explain what the hell it is you're reading, it makes enjoying it almost impossible.
Then we have the other "classics" they teach in school, of which my most prominent memory is Jekyll and Hyde, which has got to be the most boring and ill paced piece of crap I've ever been forced to sit through. Again it's old and written in overly long winded format (not to Shakespeares level) but even if it wasn't it's still just so boring. Nothing happens for like 2/3 of the way through, everything that does happen is implied and when it gets around to revealing anything it's not even interesting, leaving the conclusion boring as well. If I never see that book again I can die happy.
And then we have the poetry. Oh ye gods the poetry. We had to sit there analysing this shit and figuring out all these hidden layers of meaning that all these pieces are supposed to represent (some of which I think the teacher just made up, frankly). My mind has never experianced such dullness.
So yeah, if kids aren't already into reading during school, then the schools themselves will probably put them right off it, judging by the crap they made us sit through.
The sad part is I sit eating my lunch in college these days, always with a book on the table in front of me, and you'd be amazed how many people give you odd looks, or ask stupid questions like "how you can sit there reading all that?" Some of them are even the adults.
