I put off reading Austen for a long time, expecting her to be too prim (and too boring :) for my taste. I was suffering from one of the vices mentioned in the title Pride and Prejudice. I was prejudiced against what I considered to be the frills and conventions of upper-class or upper-middle-class British society.
I suppose I suffered from the other vice as well. As a reader of really "deep" books, I was too proud to occupy myself with anything that I thought might be superficial. When I finally did get around to reading her novels -- I've now read all of them -- I was surprised at how much I liked them. In my opinion, few writers can match her wit and insight into human nature.
Besides that wit and insight into human nature, she knows how to tell a love story. That's saying a lot. One of the best novelists ever, in my opinion.
If you’ve read Pride and Prejudice you might enjoy a miniseries that aired a few years ago. It’s called Lost in Austen and is a quirky, but captivating way of telling the story. I have no idea if it’s on any of the online movie sites. It was on Amazon when I saw it, but that was quite a few years ago.
