Fiction Adaptation Unit- Deciding on an essay subject.

I have been giving the book and film I want to discuss in my Fiction Adaptation essay some thought this weekend, as I have been at home in Nottingham, and have had some time to unwind. I re-watched a film called "The Shining" directed by Stanley Kubrick, when I suddenly decided to research the movie and find out if it was adapted from a novel.
After a quick google search, I found that it indeed was adapted from a book called "The Shining" which was written and published in 1977 by Stephen King. I also found that a television series based on the story was created too. I have since ordered the book, and have brought the Shining DVD back to University with me to study.
I am a massive fan of the work of Stanley Kubrick, and I am also a big fan of horror films and horror stories in general, so I am very happy that my personal interest has become useful for this unit.

The book version of "The Shining", released in 1977 by Stephen King.

The DVD version of "The Shining", a movie released in 1980.

As I researched online, I also found that Stephen King has been quoted as being unhappy with Kubrick's adaptation of his story as it "ignored key plot points" from his book. This intrigued me, and I believe it may be a point worth bringing up in whichever essay question I choose, that the director of the adapted book has to not only try and please the fans of the story, but also the stories original creator.
