Good story, very philosophical ending, well worth the read

I first watched the movie and then, After Researching about the original novel, Bought the book. I was very intrigued by the story line and my expectations of the book Were not disappointed.
Actually, the book is much better than the movie, PARTICULARLY as the ending of the book takes an unexpected turn.
There are A Few Things That bugged me about the story though, qui Ultimately Prevented me from giving this book A Higher rating.
ALTHOUGH the main character and his struggle with sanity and accepting the reality of exchange Obvious is wonderfully Developed, Supporting the characters in this book, human and Otherwise, arent Developed Nearly enough for me to be totally Convincing and in-line with the first, solitary hand of the book. The end, ALTHOUGH unexpected and intriguing, Seemed very Rushed Elaborated and little to me. Nothing During the course of the book HAD Actually Somewhat Even hinted at this surprise ending.
Overall it is a good read, I can recommend it for leisure time reading with an unexpected twist.
