Adapting Books into Movies

I think that the movies of Harry Potter were better than the book. There is not that many movie adaptions that have been better than the book. When books are made into movies and you have already read the book, you notice that they change many things, which might have had a very good meaning. The books are more descriptive and it lets you use your imagination more. Settings, events, and characters that were in the book get changed throughout movies which make the movie less meaningful.
