Book vs The film

Point 1 - The film had a big difference to the film, the film was more a mixture of "Romeo and Juliet" and "GTA". The book took place in the middle age, but the film was placed in the actuallity.
In the film they fight with their tuning weapons, and in the book they fight with swords and knifes.

I this case the film has more content then the book, and much more detail than the book.
I prefered the film, because it was much more entertaiment than the book.
