Roots is the only one that I haven't read - at some stage in my life. As you say, perhaps next year. Though my un-read pile is so big, probably not.
Don Quixote is didactic? Wha? Which translation is this? If it's so didactic, why did Cervantes get in so much trouble with the authorities for not depicting the clergy with sufficient respect?
Ayn Rand on the other hand... never mind the politics and philosophy, the sex scenes are cringe-worthy.
He got in trouble with people whom didn't align with his ethos. It got him into trouble easily because his intentions were so obvious, not that it validates their pettiness.
I've only read CS Lewis. Monster and I read it together before the movie came out in 2005 (she was six). It was her first taste of "the book is always better." They cut her favorite scene. She was royally pissed. As a Christian, I much prefer this type of lesson over the brimfire and hellstone spewed from a pulpit I grew up with.
I only read this series for the first time a few years ago. I don't know how I'd feel if I'd grown up with it, or if I grew up in a more Christian household. I actually think most of it is rather vague, with a few more obvious bits like who can see the lion. It's nothing on the radar compared to His Dark Materials.
