Book or Film?

Last day I finished reading the third part of the Lord of the rings. And I really missed some things in the film that happened in the book. The historys of the books are much more complex than in the films. I asked some friends about It who also had read some other books that have a film version of the history, and they told me the same.
So I recommend to all the people to read more, let your imagination spread and flow, because you can imagine what you want when you read and you aren't limited by the imagination of a director.
