Initial reaction to 'David Copperfield'

I began reading David Copperfield and my first impression was that it was going to be a book along the lines of the fantasy genre. I thought it was something like 'Benjamin Button' and I was growing fond of it mostly because of chapter one, when David said he remembered his birth. This sounded a bit like fantasy because I misunderstood it.  Also, in chapter one I didn't understand what they meant by the word ‘caul’. I looked it up and there were two definitions that could be fit into the text. As I continued to read I noticed that David Copperfield’s mother was a lady that got around since she's been married about four times. After reading the nine chapters, I noticed the book wasn’t going a fantasy and the book started to be different. I love to read fantasy books and mystery books so the book David Copperfield lost my attention when i noticed it wasn’t anything near those genres. However, I’m always open to try new things and so far the book hasn’t lost my attention but hasn’t excited me either so I’m hoping the book will get better.
