Just because they're "classics" doesn't mean they're all good. Sometimes teachers don't pay attention to what they assign BUT the good classics make you think, expand your vocabulary, teach you about lifestyles in other ages and open your mind to new ideas
In my opinion. There's only a couple that I actually like. I like modern books tbh. And classic novels make me doze off. But classical novels aren't that bad though. They're alright I guess. But they usually use lots of vocabulary.
So we can see how classic literature has developed from when classic writings were written until now. You can compare how most author wrote back in time and compare it to now. The most important thing about reading classic novels is how I can push my level of thinking to begin to understand or identify what it's about. It makes you a stronger thinker and reader.
They're tough to get through because they're written by REAL people. The author of Gone With the Wind had lived during slavery times. The author of To Kill a Mockingbird, Harper Lee, grew up in that Depression era (I think). S.E. Hinton, author of The Outsiders, grew up in those times when it was Greasers versus the preps, which is kind of how life is right now.
Classic novels carry important themes. Since you asked this question, it seems like you don't care for classic novels anyway, so most of our answers will be ignored. Just plow through it.
