I'm sorry, but I absolutely loathed it. Holden Caulfield is the most pretentious person alive, and everything he says makes me think of The Lonely Islands' "I Threw it on the Ground". The best aspect of CitR is that it gives teenagers a character they can relate to within literature, which is great since there is a worrying decline among teenagers towards reading. I just never related to Caulfield as a character is all. I will say that I did find many of my favourite books in school, such as The Great Gatsby by F. Scott Fitzgerald, Blindness by Jose Saramago, and my all-time favourite book, Brave New World by Aldous Huxley.
I also was just thinking and I have another book suggestion that's an excellent choice for people who don't like to read all that much:
The Curious Incident of the Dog in the Night Time by Mark Haddon
To me, this was an eye-opening book on the perspective of those with autism. It details a young man's journey to figure out who killed his neighbour's dog, Wellington. Throughout his travel we learn about what he thinks about, and what he doesn't understand. It's a very humanizing novel! What I also enjoyed was how accessible it was as a book. I've lent it to many of my friends who 'hate reading'.
