I can't remember details since it was in HS, but reading The Catcher in the Rye was a painfully slow and boring process. I didn't get the story, the meaning, the struggle. It was a guy complaining about everything and being miserable and then I had to write a book report about it. Icky, icky, gross.
Maybe if I read it now it'll be different but I dun wanna!
I enjoy reading unreliable narrators, and so while you're totally correct. Holden is nothing more than an angsty privileged teenager who is angry at the world. That's what made the book fun for me, at a certain point his self serving lies and his cringe attempts to act like an adult are just funny.
I've found it's a good litnus test for people, just like Fight Club or Rick and Morty. You're absolutely allowed to like these pieces, but if you think those charcters are admiral than it's a super duper red flag.
