Yeap, I´m getting the feeling it is...gulp.
I´m in Ch.1 and am already having a hard time decyphering the language used!!!
The book I have is the one which includes the final chapter, 21....apparently, the version that came out in the US is the one that Kubrick based his film upon even though it was missing that final chapter.
I´ll have to read the book, then see the movie, and then compare to see if there´s much of a difference.
So the general concensus is "weird & disturbing", eh? lol
Guess I´m in for quite a ride then... 
Thanks guys!
