Why do people hate Great Expectations?

I understand that Charles Dickens is not for everyone and his books can get boring at points. Though I like his books because I feel he was one of the first authors to have his books focused on the lower classes. When most authors before him only wrote about the super wealthy. Out of all his books I see people often hate on Great Expectations in which I feel is a story on assimilation on trying to fit into a society that will tolerate you but will never truly accept you. I related a lot to Pip’s struggles as a first generation American. Though I’d like to hear why people don’t like it, cause I feel I’m the only one who does like the book.
