I have read Candide--three times, in fact--as reading assignments for school. I remember vividly that my first reaction upon being required to read it in college was to think, But I already read this in high school! I don't want to read it again. It's not fair!
Notice that I was NOT thinking, I've read this once, and I know it so thoroughly that it is ridiculous to require me to read it again. No, with me it was more like, I've read it once and mercifully forgotten every last word of it except for the phrase, "We must tend our garden." and I never want to read it again!
On the other hand, I never had to read Sylvia Plath's The Bell Jar for school, for which I am thankful. I once had to read Plath's poem "Daddy," and that was enough to turn me off of Plath for life. lrodell assures me that The Bell Jar is worth reading, though, so I might give it a shot.
I had to read Jude the Obscure for 12th grade English. Sheer torture.
I read 1984, Brave New World, and A Clockwork Orange right after each other in 11th grade, immediately followed by Ayn Rand's We The Living. Of them all, I enjoyed We The Living the most, followed by Brave New World. The reason? Brave New World had color in it. I totally hated 1984 because the mental imagery, even more than the texztual message, was dingy, dull, and gray. The book made me feel as lifeless as the society it depicted.
I was surprised that Frankenstein was not on the list of banned books. I'm also surprised that Venus in Furs isn't on the list, either. There's also a Sherlock Holmes book by Michael Dibdin that posits that Sherlock Holmes was Jack the Ripper, which I think ought to be on the banned list simply because it is sacrilege. (g)
Okay, me being a major Holmes fan aside--Jack the Ripper was a real person. He murdered real woman. To say that a fictional character was the real killer is just absurd and insulting.
