Never Judge a Book by its Movie

I know this is a very subjective topic and feel free to disagree with me. To my mind the book is always better than the movie adaptation of it. A lot of details are lost between the page and the screen. A book works jointly with the mind in building an imaginary world. As for a movie, it does all the work for you – our personal reading becomes attached to another person's (screenwtiters', film director's, costume designers', etc.) vision and imagination.

So I asked my friends and colleques about their "good book, bad movie" experience and created a list of 7 bad and flat movies based on very good, powerful and adventurous books:

Good book/graphic novel	Bad movie
Bag of Bones  by Stephen King (M)	Bag of Bones
The Golden Compass by Philip Pullman (M)	The Golden Compass
Gulliver's Travels by Jonathan Swift (M)	Gulliver's Travels
A Princess of Mars. Mars Trilogy   by Edgar Rice Burroughs (M)	John Carter
The League of Extraordinary Gentlemen by Alan Moore (M)	The League of Extraordinary Gentlemen
Never Let Me Go  by Kazuo Ishiguro (M)	Never Let Me Go
The Time Traveler's Wife by Audrey Niffenegger (M)	The Time Traveler's Wife

However, I have to admit that great films can benefit the reading process. For example, Peter Jackson's The Lord of the Rings movie helped me get a clear understanding of the plot of the J.R.R.Tolkien’s complex fantasy work. I had no problem reading the book and imagining vivid characters as Jackson represented them. 

By the way, the HBO's medieval fantasy television series Game of Thrones encouraged me to read the book A Game of Thrones (the first book in the Songs of Ice and Fire series) by George R.R. Martin. What an amazing epic novel! And so I return to my initial statement: the book is always, always better than the movie.
