I read it a couple years ago. If you're not actively looking for the greater meaning, symbolism, etc, etc, it's a bit of a confusing read at times. My favorite part of the book is not actually the book itself, but rather many library's response to it. Fahrenheit 451 is a book all about the dangers of censorship, yet it is one of the most censored books out there. I've always hated censorship on a personal level. Banning books simply because it challenges the idea of banning books? The mere idea of something so ludicrous makes me want to hit whoever passes the bans upside the head with an encyclopedia. Why am encyclopedia? Encyclopedias used to not only be banned, but were burned on sight. Nowadays, they're the only book in the library that nobody, not even a Texan, would think to ban. Censorship of books is decreasing drastically, but even the classics are still banned in schools and public libraries. The only reason Fahrenheit 451 is banned is because people don't want to admit that the idea of banning books is an outdated and outright stupid practice. Just because a book doesn't align with your ideals means that nobody should have the right to read it? That's like saying you hate all black people and want to segregate whites and blacks because god forbid they influence each other.
Wow, I got off topic. Anyway, Fahrenheit 451 is a great read. It's also pretty short so it shouldn't take too long to read. I would highly recommend rereading it a few months later in order to pick up on a few new things. The book does a great job at being straightforward with the main message but hiding a few little small morals and ideas throughout the book, so make sure to be on the lookout for symbolism and connections.
