For every person that reads a book, a new image is created in the mind of the reader.
Just to think, millions upon millions have read the Harry Potter books.
That means milliona and millions of veiws are created.
Pick just one person to create a movie from a book, any book.
It's not going to be the same. He or she will add ideas that he or she thought from reading the books.
If you were able to redo the Harry Potter films, what would you change? Whold it make it better. Keeping to even the smallest of books, could make the longest of movies.
To add to the top of that, they must cut parts that have no meaning or that, just did not work.
Please try to keep that in mind, be lucky they are becoming films...
Have a nice day and night...
