• What do you think are the problems of making films based on books ?

Money talks... directors will, I think turn a book into a film if the author is well known, and the rest depends on the directors style, the way he sees things through his eyes. Just my opinion!

In my opinion most books that are made into films aren't worth that good. As you already said the central idea is often forgotten. The author's purpose get's forgotten. It's important for the director to make money, so things get changed. The suspense is often pushed and so the film differs from the book.
Only films that stay close to the version of the book are good because I think the film

I think if the source movie is the book, the only book to fully reflect the real events and characters. And only a book can convey the author's every word the whole idea works of literature. This doesn't apply to the film, which is based on the plot of the book.

It may suffer as a consequence, the reliability of historical fact. For example, the conspiracy, as you said. We did not consider the book as a historical encyclopaedia? Do not you?
More importantly, the book possible words t

The film enables us to reinforce our imaginations of certain parts in the book. We can either think "Wow, that's exactly how I imagined the scene, great work!" or "Hm, my vision was more beautiful".
