If the book does not do justice ...

The film is not particularly convincing.
I myself have recently completed the book and have to say that neither the acting nor the selection of scenes convinced.
So the figures are for me not shown credible and the story is too much cut together in the film.
Everything follows one another directly, where there were scenes in the book.
In addition, the story would be partly modified so that it no longer fun made the interesting story continues, at least as a film to pursue.
As has already written quality of the video does not match that of the book.
