Could you please expand on this? This book is on my to-read list, but I'm not sure I'll ever get around to reading it. Wasn't it very repetitive?

I read it since Tarr is one of my favorite directors and I saw the movie recently (the author works closely with Tarr on the screenplay and on set). It's dark, very dark but full of humor and great visual descriptions. It adds a lot to the movie, although they are separate works.
