Catcher in the Rye is quite possibly the worst book I've ever read. I'm sorry, but a psychopath kid who complains about every single little thing throughout the whole book, not to mention swears every other word... I got to the point I didn't even sympathize at ALL with him; I just wanted him to shut up and shape up. He was so immature. I loathe this story.
Of Mice and Men was also really awful. I hated all the events; it was depressing and messed up, not to mention the swearing. Oh, the horrible swearing! (And again, immature characters.)
Seriously, any book that has as much profanity as those stories... I'm sorry, no matter how "good" it is, I will not enjoy it one bit, regardless. The same goes for movies like that. That's why I normally don't like rated-R movies. If it's R for violence, that's different (I loved Air Force One, for example). If the profanity (or other certain things) is what makes it R, no. Certain things I'm sure I would enjoy if they were censored. (The movie Speed comes to mind; I love the plotline and everything, but the language infuriates me. I'll only watch it when they put it on TV.) But Catcher in the Rye and Of Mice and Men...I hated the plotlines and characters, as well.
