The thing about art, of any form, is that there are no objective standards. Many people read novels that are considered "classics" and get absolutely nothing from them. Others read "trash" and find personally relevant meaning.
Taste in art is not that different from taste in food in that most people tend to like the same things. Chocolate, for example, is almost universally loved - but there are still people who don't like it. People who love chocolate don't understand how someone could not like it, and vice versa.
Take for example, the Twilight books and movies. I loved the books, but didn't care for the movies. Take a poll, and you'll probably find ever possible combination: hated both, loved both, only liked the books, and only liked the movies.
Who is right? Everybody! Each person looks at art through the filter of their own tastes and experiences.
