I agree about clarity, so this is just an aside but that's what makes it a fun experience for me. It's unlike reading anyone else (although I haven't read many authors). I'd say no country for old men was still pretty straightforward, but I had to re-read sentences and whole paragraphs with blood meridian.
The work makes it worth it, makes it that much more rewarding to me personally. It's like choosing to play a difficult videogame, because you know once you overcome it, it'll be great.
