I'm talking works by Kurt Vonnegut, Isaac Asimov, Joseph Heller, Stephen King, Art Spiegelman, Elie Wiesel, Daniel Keyes, etc. I haven't read any from these I've mentioned, I just have a bias that tells me they're overrated trash. I think it's quite common on american "classics" (not just books but also films) a certain political defeatism or instead a very liberal surface level criticism of "bad things" (Steinbeck stays winning). And then these barren ideas get louded as incredible literature classics (which makes sense as far as the rulling class's efforts for maintaining the status quo are concerned).
But as I've said this is my analysis a priori of having read such novels, but are there actually redeeming qualities on those novels that make them worthy of pursuing? I'm not that interested in style but I can see that some of the authors mentioned have that idiosyncrasy going for them. Also I'm sure some do get the problems they're writing about and maybe that analysis, even if it doesn't go all the way, is a good enough quality.
(I write this about american novels in particular but it clearly expands to other 'classics'. Unfortunately I have read stuff by that Orwell fella which is a clear perpetrator of the crimes I've mentioned. I focused on the american side because most of the 'classics' lists are filled with them (they're anglocentric in general but more american-sided))
Isaac Asimov is decent, and I enjoyed his "robot" stories, which if anything seem like the opposite of defeatism. He even wrote an article shitting on Orwell. By the way, if you find sci-fi to be your liking, do check out Dune by Frank Herbert. I think it's an excellent series, as you may be able to tell.
