I read Fahrenheit 451 the summer before I started high school, and I really didn't like it. Granted, it was required reading (which, in my opinion, can often make a fine book seem awful and tedious), but still. I remember thinking it was confusing and very strange/surreal (and not in a good way).
But it's such a wonderful concept and I was young then. That same copy of the book (with my highlighting and pencil notes) still sits on my shelf and I really hope I get around to re-reading it someday. In honor of Mr. Bradbury.
