About 25 years ago, after being absolutely blown away by
Crime and Punishment, I gave
The Brothers Karmazov a try, and was disappointed to find it was very soap-operaish. I really couldn't care less who was sleeping with whom or about the other petty melodrama in the book.
I also recently came back to Crime and Punishment, and found that while it has some of the greatest passages I've ever read in any book, passages that are full of keen psychological penetration and empathy for deeply flawed people, there's also a lot of corny, cliche material in it: the murderer with a heart of gold, the prostitute with a heart of gold, the consumption poor mother sacrifices everything for her chldren, etc...
These sorts of characters might not have been cliche in the 19th Century, but they certainly are today.
