The Lord of the Rings books/movies. I loved them so much growing up, read them several times each and I hated some of the casting as well as a lot of the changes that were made when they presented them as movies. One was so bad I walked out of the theater. I think the majority of people that really liked the movies never read the books.

I have heard many views of Lord of the Rings! Like how the movies are amazing but the books are too slow, or how the books are amazing and the movies are amazing. Sorry to hear you didn't like the movies. 
I was just going to start up the Fellowship of the Rings, do you think the book gets too boring or drawn out in some places? I've only seen parts of the movie, so I can't really post my opinion on that either, lol.
Oy. I've loved this book all my life; read it for the first time as a little girl. Have read it several times as an adult. I laugh, I cry, I fall in love with the characters, my heart hurts for the little girl without her father (my father died when I was 16, so I identify with how she might feel) I grin like the Cheshire Cat when Meg saves the day.
I was so excited to see the (recent) film available on Netflix. Then I watched it.
It was awful. Rather than being ethereal beings, Mrs Who, Mrs. Witch and Mrs. Whatsit are goofy carictures of children's imaginary friends. The Happy Medium was a drag queen's interpretation of a Tibetan Monk. The novel has existential and religious themes; the film had neither.
Not only was it a bad adaptation of the book, it was just a bad film.
LOTR isn't true to the novels, but the films tell a good story (not exactly the real one), are expertly filmed and the acting was excellent, at least.
I loved reading
Dune by Frank Herbert. Absolutely loved it! Ever since I saw the movie, which stunk, my memories of the book have been tainted. I still love the book, it just that every time I think of it I get a companion, cringe worthy memory of the movie.
